It is a current-production part, still in the active catalog. Short-circuit breaking capacity is 50 kA at 400 V AC, 100 kA at 240 V, and 10 kA at 500 V — sufficient for most industrial distribution panels with a transformer upstream. The unit also detects phase failure, a common cause of single-phasing motor burnouts.
The 45 mm width (3-module) footprint fits standard distribution boards. Any mounting position is permitted, with zero clearance required at the sides and rear — no derating for side-by-side installation. Screw-type terminals on both main and auxiliary circuits accept 1–2.5 mm² solid or stranded (two conductors per clamp) and 2.5–6 mm² (two conductors). AWG equivalents are 14–10 for the main contacts. Depth is 96 mm, height 97 mm — a compact package that leaves room for wiring ducts and adjacent components on the rail.
The part carries a substance prohibition date of 01.05.2012, indicating RoHS compliance from that date onward.
