The 690 V rating still holds at 187 kA, so it handles 690 V line-to-line systems common in heavy industrial plants.
Physical Fit & Panel Integration
Fine for indoor panel mounting; keep it out of washdown zones.
Protection Features
Ground-fault monitoring is built in via summation current formation on the L-conductor — it measures vector sum of phase currents to detect leakage to earth. This is a yes/no ground-fault protection function, not a full residual-current device, but it covers the common case of a bolted ground fault in a solidly-grounded system. No undervoltage release, no voltage trigger, no communication function — this is a straight line-protection breaker. If you need remote trip indication or undervoltage coil, you're looking at a different variant in the 3VA family.
