The breaker also includes phase failure detection, which prevents single-phasing damage on a three-phase motor.
That is a Type 2 coordination rating — the breaker clears a bolted fault without welding its own contacts or damaging the upstream contactor, assuming the manufacturer's coordination tables are followed. The 100 kA figure holds across the full 400–690 V range, which is unusual for a 45 mm-wide device; most compact breakers derate above 480 V.
Clearance requirements: 50 mm above and below, zero forward or backward, and 30 mm to the side. Any mounting position is permitted.
The lifecycle stage is recorded as current production. No phase-out notice or last-time-buy date is on record.
