Its interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V, and still holds 187 kA at 500 V, dropping to 3.7 kA at 690 V. ## Undervoltage release and protection design That means the breaker trips automatically when supply voltage drops below a threshold, protecting downstream loads from brownout conditions or preventing automatic reclosure after a dip. The design is starter protection, so it's intended for motor branch circuits where loss-of-voltage protection is part of the safety sequence. No auxiliary switch, no ground-fault monitoring, no communication function on this order code. Maximum power loss is 6.5 W, manageable in a typical IP54 steel enclosure without forced ventilation. No trip indicator, no voltage trigger, no phase failure detection on this variant.","metaTitle":"Siemens 3VA2163-7MS36-0CA0 SENTRON MCCB, 63 A, 3-Pole, UVR","metaDescription":"Siemens SENTRON 3VA2163-7MS36-0CA0 molded case circuit breaker, 63 A, 3-pole, 330 kA at 240 V.
