Interrupting capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. For a 20 A frame, those numbers give plenty of SCCR headroom for most distribution panels — you're not bumping up against the breaker's limit on a typical 415 V line. The 3VA1020-2ED36-0AH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That gives you a dedicated alarm contact for remote fault indication — handy for a PLC input or a panel lamp.","metaTitle":"Siemens 3VA1020-2ED36-0AH0 3-Pole MCCB, 20 A, TM210, 52.5 kA","metaDescription":"Siemens SENTRON 3VA1020-2ED36-0AH0 molded case circuit breaker, 3-pole, 20 A rated continuous current, TM210 thermal-magnetic release, 52.5 kA at 240 V.
