Short-circuit protection is fixed at 10 x In (500 A magnetic trip), so it holds motor inrush without nuisance tripping on a 50 A feeder. The thermal-magnetic TM210 release provides line protection — suitable for cable and general load protection, not motor overload (no adjustable class). ## Built-in accessories for a tight panel build The UVR drops the breaker on loss of control voltage — typical for emergency-stop chains or undervoltage protection schemes. Auxiliary and alarm contacts give the PLC a hard-wired status of the breaker position and trip condition without needing a separate monitoring module.","metaTitle":"Siemens 3VA1050-4ED32-0CH0 Circuit Breaker, 36 kA @ 415 V, 5","metaDescription":"Siemens 3VA1050-4ED32-0CH0 IEC frame 100 breaker, class S, Icu=36 kA @ 415 V, 3-pole, TM210, In=50 A, UVR 120-127 V AC.
