It carries a continuous current rating of 100 A at 40 °C, with minimal derating up to 70 °C (91 A at 70 °C). The interrupting capacity is 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — covering most industrial low-voltage fault levels.
At 690 V the same breaker still clears 7.5 kA, which is adequate for most 690 V motor circuits. The 3-pole design handles three-phase loads. An undervoltage release is built in, and the auxiliary switch configuration is two HQ auxiliary switches plus an undervoltage release (UVR).
