It is designed for line protection in distribution panels and motor control centers, with a maximum interrupting capacity of 187 kA at 240 V AC and 121 kA at 415 V and 440 V. The high SCCR at 240 V makes it a fit for fault-current-heavy industrial services where a standard MCCB would cascade upstream. The 63 A frame holds its rating flat through 70 °C — no thermal derating curve to calculate. That simplifies panel design in warm enclosures or near heat-generating equipment. The interrupting ratings drop with voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The breaker includes a trip indicator, a voltage trigger, and a communication function — the latter allows remote monitoring or integration into a higher-level energy management system. Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard MCCB footprint for 3-pole 63 A frames. The shunt trip and auxiliary switches are wired via the factory-supplied terminals; no additional wiring accessories are required for basic line protection.","metaTitle":"Siemens SENTRON 3VA2163-5KP32-0JH0 MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-5KP32-0JH0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA at 240 V.
