Breaking capacity is the headline here: 330 kA at 240 V, 242 kA at 415 V, and 3.75 kA at 690 V. The 40 A rating holds flat from 40 °C through 50 °C, then derates gradually to 34 A at 70 °C. That's a clean thermal curve — no surprise drop at 45 °C like some breakers. If your panel ambient runs hot, you still have 38.5 A at 55 °C and 37 A at 60 °C, so a 40 A feeder on a warm busway isn't automatically a derate problem. The IP40 front face keeps fingers out of the live terminals but it's not sealed for washdown. That gives you two separate signal paths for status feedback — one for the breaker position, one for the alarm contact that closes only on a trip event. The integrated auxiliary trip module carries order code 3VA9908-0BC11, and the basic switch variant is 3VA2140-7JQ32-0AA0 if you need a baseline version without the communication stack. Power loss is rated at a maximum of 2 W, which is negligible for panel thermal budgeting. The ETU560 electronic trip draws its own operating power from the line current via current transformers — no separate control power needed for the trip unit itself, though the communication function may need a 24 V auxiliary supply depending on the network interface. For compliance documentation, the SENTRON 3VA2 series carries IEC 60947-2 certification as a molded case circuit breaker. RoHS and REACH declarations are standard from Siemens for current-production parts.","metaTitle":"Siemens 3VA2140-7JQ32-0EH0 SENTRON MCCB, 40 A, 3-pole, Line","metaDescription":"Siemens 3VA2140-7JQ32-0EH0 SENTRON molded case circuit breaker, 40 A rated current, 3-pole, line protection, ETU560 release, 330 kA at 240 V.
