This is the kind of breaker you spec into a distribution panel feeding motor control centers or general power loads, where you need a reliable overcurrent trip without communication or ground-fault monitoring built in.
This breaker's interrupting rating climbs with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
At 55 °C it drops to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. The maximum power loss is 17.3 W, which is modest for a 63 A MCCB but worth factoring into your enclosure's thermal budget. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount arrangements.
Auxiliary switching and trip indication
The trip alarm switch changes state only when the breaker trips on fault — not on manual open — so you can wire it into a PLC or alarm panel to flag a downstream short or overload. A trip indicator is present on the front face, giving a visual confirmation without needing to read the aux contacts.
