The minimum trip setting is 95 A, and the maximum is 756 A, which gives you a broad adjustment band for coordinating with downstream branch breakers. ## Thermal performance and panel fit Power loss is 5.4 W maximum, which is manageable for enclosure heat calculations. ## Communication and monitoring features This variant includes a communication function, which means it can report status and trip events to a higher-level control system — useful for remote monitoring in a plant SCADA setup. It also has a ground-fault monitoring version using summation current formation on L + N conductors, so it can detect leakage to ground without a separate GFCI module. The trip indicator is not present on this version, and there's no undervoltage release or voltage trigger built in.","metaTitle":"Siemens 3VA2063-6KQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-6KQ46-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, 187 kA breaking capacity at 415 V.
