The 52.5 kA breaking capacity at 240 V gives it headroom for high-fault panel feeds; at 415 V it still interrupts 32 kA, and at 690 V it holds 7.5 kA. That makes it a solid choice for main or feeder protection in a 400 V distribution board where you need selectivity with downstream breakers. ## Panel fit and auxiliary configuration The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON panelboard or a DIN-rail adapter without surprises. It ships with three auxiliary switches (HQ design) and the undervoltage release already fitted, so you don't need to order separate accessory kits for common signaling and trip-coil functions.","metaTitle":"Siemens 3VA1020-2ED32-0DD0 SENTRON MCCB, 20 A, 52.5 kA at 24","metaDescription":"Siemens 3VA1020-2ED32-0DD0 SENTRON molded case circuit breaker, 3-pole, 20 A rated at 40 °C, 52.5 kA breaking at 240 V.
