That thermal profile means you can run it near full nameplate in a warm panel without oversizing the frame. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The design is specifically for motor protection, with phase failure detection built in, no undervoltage release, and no ground-fault monitoring version. ## Panel fit and power loss Maximum power loss is 99 W, so plan for that heat in the enclosure: it's not a sealed-box part unless you've got ventilation or a bigger can.","metaTitle":"Siemens SENTRON 3VA2450-5MN32-0AA0 MCCB, 500 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2450-5MN32-0AA0 molded case circuit breaker, 500 A continuous at 40 °C, 187 kA at 240 V, 3-pole motor protection design.
