This makes it a solid choice for a motor protection circuit in a crowded enclosure where heat buildup is a given. Breaking capacity hits 330 kA at 240 V and still delivers 242 kA at 415/440 V, dropping to 187 kA at 500 V. At 690 V it manages 3.7 kA — enough for the high-voltage tail but not the primary interrupt rating. ## Motor Protection and Auxiliary Hardware This MCCB is explicitly designed for motor protection, with phase failure detection built in. That means it will trip on a lost phase before the motor single-phases and cooks the winding — a common failure mode in older plants where a fuse blows and nobody catches it until the smoke appears. That is a standard safety requirement on motor feeders in many jurisdictions — no separate UVR module to buy and install. Two HQ auxiliary switches are also integrated, giving you status feedback for the PLC or a remote annunciator without adding external contact blocks. Power dissipation is 6.5 W max at rated load, so thermal rise in the enclosure is manageable. No forced cooling required unless the panel is already dense with other heat sources.","metaTitle":"Siemens 3VA2163-7MN32-0CC0 MCCB, 63 A, 3-Pole, Motor Protect","metaDescription":"Siemens SENTRON 3VA2163-7MN32-0CC0 molded case circuit breaker, 63 A at 70 °C, 330 kA at 240 V.
