Product details

It carries a 15 kA breaking capacity per IEC/EN 60898-1 and a 30 kA rating per IEC 60947-2, with a UL 1077 listing at 5 kA for North American installations. Rated for 400 V AC at 50/60 Hz, it occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and a quick-assembly fastening system.

Dual-rated under IEC/EN 60898-1 (15 kA) and IEC/EN 60947-2 (30 kA), with a UL 1077 listing at 5 kA for supplementary protection in North American panels. The sealable design and halogen/silicon-free construction support compliance documentation requirements for RoHS, REACH, and low-emission installations.

Snap-on DIN-rail mount, any position. Combined top and bottom terminals simplify busbar and cable routing. Neutral conductor is not switched — the 3-pole design handles line conductors only.
