The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — numbers that tell you this breaker is sized for high-fault industrial panels, not light commercial distribution. The shunt trip lets a safety PLC or E-stop circuit drop the breaker remotely — common on machine-tool and conveyor infeed panels. No undervoltage release, no ground-fault module, no communication stack. This is a straight line-protection MCCB with a remote-trip option, not a smart breaker.
At 55 °C it drops to 120 A, at 60 °C to 117.5 A, and at 70 °C to 112.5 A. No rewiring needed if you're swapping from a 3VA1112-5EF32-0CA0; the line and load lugs land in the same positions.
What the interrupting ratings mean for coordination
At 240 V the 187 kA SCCR lets this breaker sit at the main or feeder position in a high-capacity transformer secondary without cascading upstream. No electronic adjustment, no zone-selective interlocking.
