USING THERMAL OVERLOAD RELAY TRIP CURVES Overview
Overload relay trip curves present trip time as a function of overload current. To use them properly, you must understand their application, construction, and limitations. Trip curves for Square D ® products assume a cold start with the coil energized at the rated voltage in an ambient temperature of 40 °C (104 °F). Different trip times would result under different conditions— conditions— if the starter coil were not energized, for example, or if the controller door were open. Ambient temperature affects the performance of the thermal overload relay (OLR). Trip times increase in temperatures below 40 °C and decrease above 40 °C. But since motor capacity also varies with temperature in about the same proportion, this variation is not normally a factor in OLR selection. Most motors are also rated on the basis of a 40 °C ambient temperature, so the 40 °C OLR trip curves allow direct comparison with motor characteristics.
Application
Trip curves are most commonly used to determine whether protection against locked rotor current (LRC) is adequate should the motor stall or fail to start. Consult the manufacturer to determine the value of the locked rotor current and the length of time that the motor can withstand this condition. Then, compare this data to the OLR trip curve to ensure that the device will trip before the motor is damaged. Trip curves can also indicate whether the OLR allows normal starting of a motor without tripping, especially in applications with a long acceleration period. For this type of analysis, calculate the rms (heating) value of the load current on the trip curve at cumulative intervals during and following the starting period. Plotting the actual motor current on the trip curve is not sufficient, because the OLR may trip even if the motor current curve does not intersect the OLR trip curve. Although the starting current falls off as the motor reaches full speed, the heat produced in the OLR (and in the motor) does not immediately dissipate. The effect of this thermal inertia can inertia can be approximated by calculating the rms current over several cumulative time periods. For an accelerating time of 15 s, for instance, rms current values might be calculated for the following time periods: 0–5 s, 0–10 s, 0–15 s, and so forth. These rms current values can then be plotted; and if the resulting curve does not intersect the OLR trip curve, then no trip should occur during startup. NOTE: If the curves do intersect at some point point beyond the motor accelerating period, period, the OLRs may or may not trip during startup. The above calculation ignores heat losses, and therefore may give a false indication that the OLRs will trip. In such cases, we recommend conducting a trial.
Curve Construction
Square D trip curves come in two basic versions:
•
Curves with one solid line (maximum) and one dashed line (average) apply (average) apply to present-production melting-alloy thermal units (plain brass nameplate only) and present-production bimetallic thermal units.
•
Curves with two solid lines (with lines (with or without shaded area) apply to older-design melting-alloy thermal units (red enamel nameplate) and older-design bimetallic thermal units.
The width of the band curve does not represent repeat accuracy of a particular thermal unit, nor does it imply a variation between thermal units of the same size. However, the thermal units of different sizes do have slightly different characteristics. These differences result in a band of values (or maximum and average values, depending on the type of curve) when data for several sizes of thermal units are included in one curve. The load scale is expressed in three ways:
• •
Multiples of trip current rating is rating is obtained by dividing the overload current by the trip current rating.
•
Percent of thermal unit number, element number, or relay rating is rating is obtained by dividing the overload current by the number stamped on the thermal unit nameplate and multiplying by 100. (For a B19.5 thermal unit, 100% corresponds to 19.5.)

Percent of trip current rating is rating is obtained by dividing the overload current by the trip current rating1 and multiplying by 100.
Also called the rated trip current or the ultimate trip current.

Calculating the Trip Current Rating
Overload Relay Trip Curves
The trip current rating is a nominal value approximating the minimum current that will trip an OLR in an ambient temperature of 40 °C. To calculate the trip current rating: 1. Refer to the thermal thermal unit unit selection selection table specifie specified d for the controller. controller. 2. Locate the minimum full-load full-load current (FLC) for the applicable thermal unit. unit. 3. Multiply the the minimum FLC by 1.25 (1.15 for Class 8198). The result is the trip current rating. This procedure applies to controllers with bimetallic OLRs if the trip adjustment is set to 100%.
Calculating the Trip Current for Ambient Temperatures Other Than 40 °C
When the controller is in an ambient temperature other than 40 °C, calculate the trip current using the correction factor shown in Fi Figu gure re 2. Trip rip Curr Curren entt
=
M × tri trip cur curre rent nt rat rating ing at 40 °C
where M is the multiplier corresponding to the temperature. NOTE: Ambient temperature is the the temperature surrounding the starter enclosure. Normal Normal temperature rise inside the enclosure is accounted for in the thermal unit selection tables.
Limitations
For most magnetic starters, the trip curves are different for OLRs mounted in small enclosures than for those mounted in large enclosures. While curves for open-type starters are theoretically correct only for devices mounted without an enclosure, these curves provide a reasonable approximation of performance using a large enclosure.
•
Small enclosure trip curves are for use with devices of the following Classes: — 8536 (start (starter er in its own own enclosure) enclosure) — 8904 (non-comb (non-combinat ination ion or non-rever non-reversing) sing) — 8998, 899 8999, 9, I-Line, I-Line, and QMB (motor (motor control centers) centers)
•
Large enclosure trip curves are for use with devices of the following Classes: — 8536 (start (starter er in its own own enclosure) enclosure) — 8539 (combinat (combination ion starter, starter, non-revers non-reversing) ing) — 8606, 8630, 8630, 8640 8640 (reduced (reduced voltage voltage starter starter)) — 8736, 8739 (reversing (reversing starter) starter) — 8810, 8811, 8811, 8812 8812 (multi-sp (multi-speed eed starter) starter) — 8940, 8941 (pump controller controller)) — any other other starter starter in a large enclosu enclosure re
Curve accuracy should be sufficient for most applications. The curves are more accurate for high currents than for low currents. In particular, overload currents below 300% may yield different trip times. Conditions in the field may differ from those in a laboratory; the longer the trip time period, the more pronounced the differences. Continued on next page

Examples
5/2005
Motor 7.5 hp, 200 V, 3-phase, 1.15 SF, 22.6 A FLC, 136 A LRC Starter Class 8536 Type SCG3 with B45 thermal units Ambient Temperature 40 °C (104 °F)
Question
What is the average OLR trip time with a locked rotor current of 136 A (6 ti mes FLC)?
Calculations
In a 40 °C ambient temperature, the trip current rating is 125% of the minimum current in the thermal unit selection table. For the Class 8536 Type SCG3 starter, B45 thermal units were selected from the 22.0–24.4 A FLC range shown in Thermal Unit Table 13 on pag age e 5. Based on the minimum FLC for the thermal unit, the Trip Current Rating = 1.25 × 22 27.5 =
With a locked rotor current of 136 A, the Multiple of Trip Current Rating = 136 ÷ 27.5
=
4.95
Solution
The trip curve index shows that curve 30068-407 should be used for a Class 8536 Type SCG3 starter in a small enclosure. For a multiple of 4.95, the average trip time shown in the curve is 19 seconds.
Question
If the ambient temperature were 50 °C (122 °F), what would the average trip time be?
Calculations
Figure Figu re 2 on page page 5 shows that the ambient temperature correction factor at 50 °C is 0.9. Trip Current Rating 1.25 × 22 × 0.9 24.75 =
=
With a locked rotor current of 136 A, the Multiple of Trip Current Rating = 136 ÷ 24.75
=
5.5
Solution
For a multiple of 5.5, the average trip time shown in curve 30068-407 is 16 seconds.
Question
If the load current were twice the FLC (45.2 A), and the ambient temperature were 40 °C (104 °F), what would the average trip time be?
Calculations
Trip Current Rating = 1.25 × 22
=
27.5
Multiple of Trip Current Rating = 45.2 ÷ 27.5
=
1.65
Solution
For a multiple of 1.65, the average trip time shown in curve 30068-407 is 170 seconds.
Question
If the load current were 28 A, what would the average trip time be?
Calculations
Trip Current Rating = 1.25 × 22
=
27.5
Multiple of Trip Current Rating = 28 ÷ 27.5 Solution
4
=
1.018
For a load current this close to the trip current rating, the trip time is difficult to predict. It would likely take hours for the OLR to trip.
