At 690 V the 7.5 kA rating limits it to low-fault locations or transformer-secondaries with reduced available current. ## Construction and auxiliary options Three-pole line-protection version with a TM210 thermal-magnetic fixed-trip release. It ships with two HQ auxiliary switches (order code 3VA9608-0BB24 for the integrated auxiliary trip) and an undervoltage release (UVR) fitted. Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — standard SENTRON 3VA footprint, drops into the same DIN-rail or screw-mount pattern as other 3VA frames. Mechanical endurance rated at 15 000 operations — adequate for a distribution breaker that cycles infrequently, not a switching-duty device.","metaTitle":"Siemens 3VA1050-3ED36-0CC0 SENTRON MCCB, 50 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1050-3ED36-0CC0 molded case circuit breaker, 50 A rated current, 3-pole, TM210 release, 75.6 kA at 240 V.
