Its interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that govern whether this breaker clears a fault without upstream damage. No communication function or ground-fault monitoring is built in, so keep that in mind if the spec calls for remote trip indication or GF protection.
At 55 °C it derates to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. Maximum power loss is 13.3 W — negligible for most panels but worth a glance in a densely packed cabinet. The 3-pole width matches the standard SENTRON 3VA footprint, so it drops into a panel pre-drilled for the series without rework.
