Breaking capacity hits 75.6 kA at 240 VAC, 52.5 kA at 415 VAC, and 32 kA at 440 VAC — numbers that tell you this breaker handles high-fault panels without cascading upstream. The 3VA1020-3ED36-0HA0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON mounting bases and busbar systems. Max power loss is 12 W, which matters for enclosure thermal calculations when you stack multiple breakers. No trip indicator on the front face — you'll need a remote status contact or a visual check at the handle position.","metaTitle":"Siemens SENTRON 3VA1020-3ED36-0HA0 MCCB, 20 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1020-3ED36-0HA0 molded case circuit breaker, 3-pole, 20 A rated current, 75.6 kA breaking capacity at 240 VAC.
