The TM210 thermal-magnetic release handles overload and short-circuit curves, and the integrated undervoltage release (UVR) lets you drop the breaker on a control signal or safety circuit. With 2 auxiliary switches plus a separate trip-alarm switch, you get status feedback for PLC or annunciator inputs without adding external relays. That thermal stability matters when the panel sits near a hot process line or in a non-climate-controlled electrical room. Mounting dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards or DIN-rail adapters. ## Interchange note vs 3VA1010-2ED42-0AE0 The 3VA1010-2ED42-0AE0 is a physically similar 3-pole SENTRON MCCB but carries a 100 A frame and a different trip unit. The 3VA1050-2ED36-0CH0 is a 50 A breaker; swapping in the 100 A variant would require re-checking cable sizing, busbar ampacity, and coordination settings. Footprint and accessory slots are shared, so a panel designed for the 3VA1010 frame can accept the 3VA1050-2ED36-0CH0 without drilling or busbar rework — but the continuous current rating must match the load.","metaTitle":"Siemens 3VA1050-2ED36-0CH0 SENTRON MCCB, 50 A, 3-Pole, 52.5","metaDescription":"Siemens 3VA1050-2ED36-0CH0 SENTRON molded case circuit breaker, 50 A rated, 3-pole, 52.5 kA at 240 V.
