Above that, it derates gradually: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If your panel ambient runs at 60 °C, plan for a 59 A continuous load maximum — not the full 63 A. ## Auxiliary contacts and shunt trip This breaker ships with two high-quality auxiliary switches (2 HQ) factory-fitted. The integrated shunt trip (STL) is wired to terminals on the front; its order code is 3VA9688-0BL32. No communication module, no phase-failure detection, and no other measurement function are included — this is a straight line-protection device. The TM210 release is thermal-magnetic, fixed-trip, no voltage trigger for undervoltage. The width matches the standard 3VA 3-pole module (roughly 3 x 25.4 mm). For DC network applications, consult the 3VA molded case circuit breaker device manual — the interrupting ratings listed here are for AC only.","metaTitle":"Siemens 3VA1063-4ED36-0JC0 SENTRON MCCB, 63 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1063-4ED36-0JC0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, 121 kA at 240 V.
