The Siemens 3VA1040-3ED36-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for 40 A continuous current at 40 °C, with a TM210 thermal-magnetic release that handles overload and short-circuit protection in a single compact package. Breaking capacity reaches 75.6 kA at 240 V AC, stepping down to 52.5 kA at 415 V and 32 kA at 440 V — enough headroom for most industrial distribution panels where high fault currents are a concern.
Dimensions are 130 mm tall, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling.
Rated insulation voltage is 800 V, and the maximum operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C. The breaker is designed for fixed installation without communication or neutral conductor retrofits.
