That flat thermal curve means the breaker holds its 63 A trip threshold even inside a hot panel near a motor starter — no need to oversize for a 50 °C or 60 °C cabinet. Three poles, shunt trip release fitted, phase failure detection built in. The 3-pole construction matches standard three-phase motor feeds; the shunt trip (STL) allows remote emergency-off or undervoltage tripping from a PLC or E-stop circuit. Rated breaking capacity of 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The 330 kA at 240 V is typical for high-fault industrial distribution panels where the transformer secondary can deliver massive short-circuit current; the 242 kA at 415 V covers most European 400 V three-phase systems. For a 400 V line-up, the 242 kA SCCR gives generous headroom for selective coordination with downstream feeders. ## Trip delay settings and motor protection logic Adjustable short-time delay from 4 s minimum to 17 s maximum, allowing coordination with downstream branch breakers or motor starters during inrush. The motor protection design includes phase failure detection, which trips on loss of one phase — critical for preventing single-phasing damage on a three-phase motor. No ground-fault monitoring version fitted on this variant; if ground-fault protection is needed, the basic switch order code 3VA2163-7MN36-0AA0 is the base platform this breaker builds on. No auxiliary switch fitted on this order code; the shunt trip release is the only internal accessory. If you need an auxiliary contact for status feedback, that would be a separate add-on module.","metaTitle":"Siemens 3VA2163-7MN36-0KA0 SENTRON MCCB, 63 A, 3-Pole, Motor","metaDescription":"Siemens 3VA2163-7MN36-0KA0 SENTRON molded case circuit breaker, 63 A rated current at 40 °C, 3-pole, motor protection design with shunt trip and phase failure detection.
