What this MCCB brings to a panel
It carries a 75.6 kA interrupting rating at 240 V and 52.5 kA at 415 V — numbers that tell you it can handle high-fault-current service entrance or distribution positions without cascading upstream.
Above that it starts to step down: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.
Interrupting capability across voltage levels
The interrupting ratings step down as voltage climbs: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V.
Auxiliary contacts and shunt trip
The shunt trip is the factory-fitted option 3VA9688-0BL32.
