That spread covers most low-voltage industrial distribution — 480/277 V and 400/230 V grids are well within the curve. The overcurrent release is the TM210 thermal-magnetic type, a fixed-trip design suited for feeder and branch-circuit protection where adjustable magnetic pickup isn't needed. Three-pole construction, 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). No trip indicator window, so visual status checking requires the handle position.","metaTitle":"Siemens 3VA1050-3ED36-0KA0 SENTRON MCCB, 50A, 75.6kA at 240V","metaDescription":"Siemens SENTRON 3VA1050-3ED36-0KA0 molded case circuit breaker, 3-pole, 50A, TM210 release, shunt trip.
