It is built for panel mounting in commercial and industrial distribution boards where selective coordination and high fault-current handling are required.
Interrupting capacity — the number that matters
This breaker delivers 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. At 690 V the 17 kA rating still covers most industrial motor branch circuits; at 240 V the 187 kA rating handles high-capacity transformer secondaries.
Thermal current rating and derating
It derates to 31 A at 55 °C and 60 °C, and to 30 A at 65 °C and 70 °C. If your load draws a steady 32 A in a 55 °C panel, you need to step up to the next frame size or improve ventilation.
The case measures 130 mm tall, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or backplate mounting systems.
