It's designed specifically for motor protection, with integrated phase failure detection and an undervoltage release built in. That UVR is the key differentiator here — it's not an add-on accessory; it's part of the base design, so if your safety circuit needs a drop-out on voltage loss, this breaker handles it without extra wiring. This breaker punches hard at low voltage: 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V. At 690 V it's down to 3.7 kA. That steep roll-off means you need to check your system voltage against the available fault current — at 480 V you've still got solid headroom for most industrial services, but at 690 V this isn't your high-fault breaker. Max power dissipation is 6.5 W, so thermal management in a sealed enclosure is manageable. No trip indicator on this variant, and no communication module — it's a straight electromechanical breaker with the UVR as the only auxiliary release.","metaTitle":"Siemens SENTRON 3VA2163-5MN32-0CA0 MCCB, 63 A, 3-Pole, Motor","metaDescription":"Siemens SENTRON 3VA2163-5MN32-0CA0 molded case circuit breaker, 63 A continuous, 3-pole motor protection design with undervoltage release and phase failure detection.
