Product details

Interrupting ratings: 6 kA, 10 kA, and 5 kA AC; 15 kA DC at 60-72 V. Rated operating voltage 400 V AC (440 V with multi-phase or single-phase), 60 V DC. The 2-pole design switches both lines but leaves the neutral unswitched — check your panel wiring if you need four-pole isolation.

Built for the route

This breaker is sealable, halogen-free, and silicon-free. The IP20 rating with conductors connected means it keeps dust out of the terminals in a typical enclosure. Pollution degree 3 — it'll handle the conductive grime you find near bearings, conveyors, or washdown stations. That's standard — drops into any SENTRON panel without rework.

Frequently asked questions
