The 3-pole design fits three-phase loads up to 690 V, with breaking capacities that step down as voltage climbs: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. The breaker also has a voltage trigger and a mechanical trip indicator, which helps during fault isolation.
The shunt trip coil and auxiliary contact wiring land on the integrated terminals; no separate accessory base is required for the HQ contact block.
Rated continuous current holds at 100 A from 40 °C up to 50 °C, then derates linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If the panel runs hot, factor the derating into your load budget — the breaker will not trip earlier, but the thermal element calibrates to those numbers.
