The overload setting is adjustable from 95 A to 756 A, giving the integrator flexibility to match the breaker to the actual load without swapping the frame. Breaking capacity drops with system voltage: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The 690 V figure is low — this breaker is not intended for 690 V main feeds; it's sized for 240–500 V distribution where the fault current is within its capability. ## Thermal Performance and Derating ## Communication and Monitoring This MCCB includes a communication function and other measurement capability, plus ground-fault monitoring via summation current formation on L + N conductors — useful for remote status and leakage detection without an external relay.","metaTitle":"Siemens SENTRON 3VA2163-5KQ42-0AA0 MCCB, 63 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2163-5KQ42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, 187 kA breaking capacity at 240 V.
