The Siemens SENTRON 3VA1032-3ED32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 32 A at 40 °C to 50 °C, derating to 30 A at 70 °C. The interrupting ratings are 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — these are the fault currents the breaker can safely clear at each voltage level without welding or rupturing. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. Maximum power loss is 13.1 W, relevant for thermal budgeting in a sealed panel.
