Breaking capacity is declared at multiple voltage levels: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. This keeps the breaker simple and repeatable for standard feeder protection where field-adjustable curves are not required. The breaker ships without auxiliary contacts or an undervoltage release as standard. A shunt trip (STL) release is designed in, order code 3VA9688-0BL30, for remote tripping applications where you need to cut power from a pushbutton or safety circuit. Above that, derating begins: 38.4 A at 55 °C, stepping down to 36 A at 70 °C.","metaTitle":"Siemens 3VA1040-3ED32-0HA0 SENTRON MCCB, 40 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1040-3ED32-0HA0 molded case circuit breaker, 40 A rated continuous current, 3-pole, TM210 thermal-magnetic release.
