It carries a rated continuous current Iu of 100 A at 40 °C, with the same rating holding at 45 °C and 50 °C before derating begins at 55 °C (96.25 A) down to 85 A at 70 °C. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — figures that cover most industrial low-voltage fault levels. The overcurrent release is an ETU320 electronic unit, and the auxiliary release is a shunt trip (STL).
Maximum power loss is 10 W, which feeds into the enclosure thermal budget for derating calculations.
Operating limits and environment
It does include a voltage trigger.
