Breaking capacity runs 440 kA at 240 V, 330 kA at 415 V, 330 kA at 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — that's enough SCCR headroom for most industrial service-entrance and distribution panels without cascading upstream.
Ground-fault monitoring uses summation current sensing on L + N — it detects leakage without a separate GFCI module, which saves a DIN space and a wiring step. Communication function is onboard, so this breaker can talk to a higher-level monitoring system for load profiling or remote trip indication — useful on a line where you want to know what popped without walking the panel. Max power loss of 7.7 W is low enough that you don't have to budget extra cooling for a densely packed enclosure.
