That derating curve is tight — only 5 A lost by 70 °C — so the breaker keeps its full rating in most panel ambient conditions. Maximum power loss is 17.3 W, which matters for heat buildup in a densely packed enclosure. Breaking capacity drops with system voltage: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. The steep fall above 440 V is typical for MCCBs; at 480/500 V the 17 kA still covers most industrial service-entrance and feeder applications. The shunt trip allows remote opening via a control voltage — useful for emergency-stop or interlock circuits. No undervoltage release is fitted.","metaTitle":"Siemens 3VA1163-6EF32-0KC0 SENTRON MCCB, 63 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1163-6EF32-0KC0 molded case circuit breaker, 63 A at 40 °C, 3-pole, 220 kA breaking at 240 V.
