Rated for the full range 20... 690 V, this unit includes phase failure detection — critical on motor loads where a lost phase can cause single-phasing and winding damage.
Panel Integration & Mounting
Mounting position is any. Clearance requirements: 20 mm upwards, 20 mm downwards, 9 mm at the side, 0 mm forwards and backwards. Screw-type terminals for the main current circuit accept 2× (0.5... 1.5 mm²) solid or stranded, or 2× (0.75... 2.5 mm²).
Coordination & Back-Up Protection
At 240 V and 400 V, no upstream fuse is required — the 100 kA breaking capacity handles fault clearance alone. The rated operational current at AC-3 maximum is 15 switching operations per hour.
