This is a line-protection design, not a motor-protective breaker — it's sized for feeder and branch-circuit duty where you need selective coordination downstream. ## Undervoltage release and communication This is common in safety circuits where a loss of control voltage must open the main contacts. The UVR is wired separately; verify coil voltage compatibility with your control transformer before panel build. The breaker includes a communication function and an other measurement function for remote monitoring and energy metering via the SENTRON bus.","metaTitle":"Siemens SENTRON 3VA2163-5KP32-0CA0 MCCB, 63A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA2163-5KP32-0CA0 molded case circuit breaker, 63A rated, 3-pole, 187kA interrupting at 240V.
