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.","metaTitle":"Siemens 3VA1050-3ED42-0KH0 Circuit Breaker, 50A, 25kA @ 415V","metaDescription":"Siemens 3VA1050-3ED42-0KH0 IEC frame 100 circuit breaker, 4-pole, 50A fixed TM210, 25kA Icu @ 415V.
