It's designed for line protection duty, meaning it protects feeders and distribution circuits rather than specific motor or generator loads. The interrupting ratings climb to 187 kA at 240 V and hold at 121 kA through 415–440 V, then drop to 75.6 kA at 500 V and 3 kA at 690 V — so it's built for high-fault-capacity distribution panels, not light branch circuits. That makes it suitable for monitored, networked distribution where you need remote status and controlled shutdown capability. ## Undervoltage release and auxiliary wiring The breaker is equipped for an undervoltage release (UVR) — when line voltage drops below the release threshold, it trips the breaker, which is standard for emergency-stop chains or undervoltage protection schemes. That gives you two independent status signals (open/closed) plus a dedicated alarm contact that changes state only on a fault trip, not on manual switching. Wire the trip alarm into the PLC or annunciator for immediate fault notification. ## Power loss and thermal budget Maximum power loss is 7.9 W at rated current. In a densely packed panel, that heat needs to be considered for the enclosure's thermal budget — it's low enough for most standard cabinets but worth checking if the breaker sits next to heat-sensitive electronics or in a sealed, unventilated box.","metaTitle":"Siemens 3VA2063-5KP32-0BH0 SENTRON MCCB, 63A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2063-5KP32-0BH0 molded case circuit breaker, 63A continuous, 3-pole, 187kA interrupting at 240V.
