The interrupting capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 76 kA at 440 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream. Thermal derating is flat from 40 °C to 50 °C at 32 A, then drops only 1 A per 5 °C step through 70 °C. That means a panel running at 55 °C ambient still delivers 31 A — no need to oversize the frame for a warm enclosure.
Mounting and integration — fits the standard DIN-rail footprint
The breaker measures 70 mm deep by 76.2 mm wide by 130 mm high — a standard 3-pole MCCB footprint that clips onto a DIN rail or mounts directly to a backplate. At 76.2 mm wide, it occupies three modular 25.4 mm positions, so you can plan the gland plate and wireway fill before the panel arrives. Maximum power loss is 11 W, which is low enough that natural convection in a typical enclosure handles the heat without forced air.
