It carries a massive 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 75.6 kA at 440 V — numbers that tell you this breaker is built for high-fault industrial distribution, not light commercial service. At 63 A continuous, this is a line-protection breaker — not a motor-protection device with adjustable overloads. Comes with 2 auxiliary switches (HQ type) pre-installed, so you get status feedback without adding a separate accessory block. Rated 63 A from 40 °C up to 50 °C, then derates gradually: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power loss is 17.3 W at full load. That's the heat you need to evacuate from the enclosure — relevant for sealed panels or high-density layouts where thermal stacking could push the ambient past the derating curve.","metaTitle":"Siemens 3VA1163-5EF36-0KC0 SENTRON MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1163-5EF36-0KC0 SENTRON molded case circuit breaker, 63 A, 3-pole, TM240 release, 187 kA at 240 V.
