The power loss at full rating is 101.5 W maximum, which matters for enclosure thermal management if the breaker is in a sealed box. No successor has been announced. The breaker measures 110 mm deep, 138 mm wide, and 248 mm high. The 110 mm depth includes the handle and the auxiliary switch block, so leave clearance for wiring and the UVR coil.","metaTitle":"Siemens SENTRON 3VA2450-7MN32-0CL0 MCCB, 500 A, 3-Pole, Moto","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0CL0 molded case circuit breaker, 500 A at 40 °C, 3-pole, motor protection design with undervoltage release and phase failure detection.
