Product details

The 4-pole (4P) configuration handles three-phase plus neutral, common in distribution panels where a switched neutral is required. The TM-D trip provides fixed thermal (overload) and magnetic (short-circuit) protection; no adjustment dials, so the trip curve is set at the factory.

Where it fits and how it connects

Mounts on a backplate (not DIN rail) in horizontal or vertical orientation, flat on the back. Front-facing Everlink terminals accept 2.5–95 mm² rigid/stranded copper (70 mm² flexible).

Listed as current production. EN/IEC 60947-2 certification covers circuit-breaker performance and safety.
