Breaking capacity is what sets this MCCB apart: 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC. At 70 mm deep, 76.2 mm wide, and 130 mm tall, this 3-pole MCCB fits standard SENTRON 3VA panel footprints. The shunt trip adds a control-wire connection alongside the power lugs; verify free-wheeling diode polarity on the trip coil if driving it from a 24 VDC PLC output — the coil suppression is internal but polarity-sensitive.","metaTitle":"Siemens 3VA1050-4ED36-0KA0 SENTRON MCCB, 50A, 3-Pole, Shunt","metaDescription":"Siemens SENTRON 3VA1050-4ED36-0KA0 molded case circuit breaker, 50A rated at 40°C, 3-pole, 121 kA at 240 VAC breaking capacity.
