Product details

Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, so it safely interrupts fault currents up to those levels without cascading upstream. The DC rating is 60 V, covering common control-circuit rails. This is a current-production part — lifecycle status is active, so it's a standard BOM line item, not a last-time-buy scavenger hunt.

Depth is 70 mm, height 90 mm — a compact footprint that leaves room for wiring ducts and adjacent devices.

Halogen-free and silicon-free construction, which matters for panels in clean-room or corrosive-gas settings where outgassing contaminates contacts. Vibration resistance is 50 m/s² at 25-150 Hz and 60 m/s² at 35 Hz (4 sec), so it holds up on machinery with moderate vibration.
