It carries a 330 kA interrupting capacity at 240 V, dropping to 3.7 kA at 690 V — the high short-circuit rating at lower voltages makes it suitable for fault-current-heavy industrial distribution panels where coordination with upstream gear matters.
Phase failure detection and ground-fault monitoring (summation current formation on L-conductor) are built in, so the breaker can trip on loss of phase or residual current without an external relay. The communication function allows integration into a higher-level monitoring system — useful for remote trip indication and load trending in a managed switchgear setup.
