It carries a continuous current rating of 100 A at 40 °C through 70 °C, meaning no derating is needed across that entire ambient range — that's a straight 100 A all the way up to a 70 °C panel interior, which saves you a calculation step on a hot switchroom lineup. Three poles, so it switches all phases on a three-phase supply. The breaking capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — that 187 kA figure at 240 V is the headline number for high-fault North American panels; the 121 kA at 415 V covers the common European 400 V distribution bus.
That gives you two NO/NC auxiliary contacts for status feedback, plus a separate trip-indicating contact and an electrical alarm contact — enough for a remote indication and a PLC digital input without adding a second accessory module.
Maximum power loss is 13.5 W — that's the heat the breaker dissipates at full rated current.
