The 3-pole design handles three-phase circuits, and the TM210 overcurrent release gives a fixed thermal-magnetic trip — no field-adjustable dials, so selectivity is set at the factory. Breaking capacity climbs as voltage drops: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. For a 415 V distribution board, the 32 kA figure gives solid headroom against most utility fault levels. Maximum power loss is 14.6 W — not negligible in a sealed panel; factor that into thermal calculations if you're stacking breakers tight. ## Auxiliary release and panel integration The supplied basic switch is 3VA10502ED360AA0, which is the internal switching mechanism. Panel footprint is 70 mm deep, 76.2 mm wide, 130 mm tall — standard 3-pole MCCB width for the SENTRON 3VA platform, so it lands in the same DIN-rail or mounting-plate slot as other 3VA frame sizes. No communication function and no trip indicator — this is a plain thermal-magnetic breaker with a remote-trip coil, not a metering or smart breaker.","metaTitle":"Siemens 3VA1050-2ED36-0JA0 SENTRON MCCB, 50 A, 3-Pole, Shunt","metaDescription":"Siemens SENTRON 3VA1050-2ED36-0JA0 molded case circuit breaker, 50 A at 40 °C, 3-pole, 32 kA at 415 V.
