It's designed for line protection duty, meaning it sits on the feeder side of a distribution panel, not as a motor starter. ## Breaking capacity across voltage levels This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. ## Electrical ratings and insulation Power loss is 2.2 W maximum — negligible for panel thermal calculations but worth noting if you're packing multiple breakers in a sealed enclosure. No undervoltage release or trip indicator is fitted on this variant, so if you need remote shunt-trip capability, confirm the accessory slot compatibility.","metaTitle":"Siemens SENTRON 3VA2040-5JP32-0AA0 MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2040-5JP32-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, 187 kA at 240 V.
