The interrupting capacity hits 52.5 kA at 240 V, 32 kA at 415 V, and 13.6 kA at 440 V — enough headroom for most industrial service-entrance or feeder applications where fault currents are high. The trip indicator gives a local visual confirmation of a fault trip — useful when you're walking a row of panels and need to spot the open breaker fast. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most panel-mounted or DIN-rail adapters in the SENTRON range. The 14.5 W maximum power loss matters for thermal management inside a sealed enclosure; if you're packing multiple breakers in a small cabinet, factor that into the cooling calc.","metaTitle":"Siemens 3VA1020-2ED32-0CH0 SENTRON MCCB, 20 A, 52.5 kA at 24","metaDescription":"Siemens SENTRON 3VA1020-2ED32-0CH0 molded case circuit breaker, 3-pole, 20 A rated at 40-55 °C, 52.5 kA interrupting at 240 V.
