Breaking capacity runs from 52.5 kA at 240 V down to 7.5 kA at 690 V, so the interrupting rating is voltage-dependent; check the specific fault level at your system voltage before committing the BOM line.
At 415 V the breaker interrupts 32 kA, dropping to 13.6 kA at 440 V and 7.5 kA at 500 V and 690 V. That voltage sensitivity matters for selectivity studies: downstream devices must coordinate within these limits. No communication module — this is a standalone line-protection breaker, not a power-monitoring node. If you need metering or remote trip indication later, the auxiliary switches give you a dry-contact signal back to a PLC input.
The breaker footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB width that fits most DIN-rail or panel-mount enclosures without surprises.
