It carries 630 A continuous at 40 °C, with a 3-pole configuration that clears faults up to 187 kA at 240 V — that interrupting capacity means it can handle high-fault utility feeds without cascading upstream breakers. The unit includes a shunt trip (STL) for remote opening and a complement of auxiliary switches: two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ).
Continuous current derates with ambient temperature: 630 A at 40 °C drops to 612 A at 45 °C, 593 A at 50 °C, and continues stepping down to 520 A at 70 °C. Interrupting capacity varies by line voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V.
The 110 mm depth (4.33 in) is the critical dimension for gland-plate clearance and back-panel wiring troughs; verify your enclosure depth allows the 110 mm plus bending radius for 630 A cable lugs.
Environmental limits and power loss
Maximum power loss is 162 W at full rated current — that heat must be managed in the enclosure thermal calculation.
