Product details

The Siemens 3VA1050-3ED42-0KH0 is a 4-pole IEC frame 100 circuit breaker with a 50 A fixed thermal-magnetic (TM210) release, rated for a breaking capacity of 25 kA at 415 V AC (class N).

Built-in accessories for control and signaling

The shunt trip lets a remote PLC or E-stop circuit open the breaker independently of the thermal-magnetic trip — standard for emergency-off or load-shedding schemes.

DIN-rail panel fit

Mounts on standard DIN rail inside the enclosure. The 4-pole footprint and integrated shunt trip occupy the same slot as a standard 4-pole MCCB — no extra panel space for external control relays.
