Three-pole construction (3P) handles three-phase circuits. The interrupting ratings are substantial: 242 kA at 240 VAC, 187 kA at 415 V and 440 VAC, 121 kA at 500 VAC, and 3.7 kA at 690 VAC. The breaker ships with two HQ auxiliary switches and an undervoltage release (UVR) pre-installed. No ground-fault monitoring is included on this variant.
The 86 mm depth is the key constraint for shallow backpanels or enclosed switchboards. In a sealed, uncooled enclosure that heat must be factored into the thermal budget — at 100 A continuous, the 12.5 W is modest for a single breaker, but a multi-breaker panel can accumulate quickly.
