The front face is IP20 — safe for finger contact inside an enclosed panel. Screw terminals on both main and auxiliary circuits accept solid wire from 0.5 to 1.5 mm² (two conductors) and stranded up to 6 mm², so it'll handle the typical control-wiring gauges you find in a motor starter bucket.
The 100 kA breaking capacity at 400 V (and at 240, 500, and 690 V) means this breaker can interrupt a fault current up to that level without welding contacts or venting plasma — critical for meeting the SCCR rating of the panel. Phase-failure detection is built in, so it protects against single-phasing on a three-phase motor. Ground-fault detection is not included — that's handled separately in the feeder or by a GFCI module. Auxiliary switch is available as an add-on (product extension auxiliary switch = Yes), transverse design, so you can wire a status signal back to the PLC or annunciator without a separate contactor block.
Zero clearance needed at the sides or rear. Depth is 96 mm, width 45 mm, height 97 mm.
