The breaker dissipates 14.6 W maximum at rated load, which matters for internal enclosure temperature rise calculations. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. ## What it does not include The TM210 release is a basic thermal-magnetic unit — no electronic adjustment, no zone-selective interlocking. If the application requires remote tripping or ground-fault protection, this base variant is not the right pick; a 3VA with the appropriate accessory or electronic release would be needed.","metaTitle":"Siemens SENTRON 3VA1050-2ED42-0AA0 MCCB, 50A, 4-Pole, 52.5kA","metaDescription":"Siemens SENTRON 3VA1050-2ED42-0AA0 molded case circuit breaker, 50A, 4-pole, TM210 release, 52.5kA interrupting at 240V.
