At 415 V it still holds 154 kA, dropping to 121 kA at 440 V, and 17 kA at both 500 V and 690 V. That's standard for applications where a loss of control power must kill the load: emergency stops, safety circuits, or remote shunt-trip schemes. It also carries 2 auxiliary switches plus a separate trip alarm switch (HQ), so the panel PLC gets both a status mirror and a dedicated fault flag without sharing contacts.
At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A.
Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a 3-inch wide body that fits standard MCCB mounting patterns. Depth of 70 mm (2.76 in) means it clears most shallow gland-plate enclosures. The trip indicator is visible through the front cover, so a walk-by inspection catches a tripped breaker without opening the door.
