The thermal-magnetic TM240 release handles overloads via a bi-metallic element and short circuits via a solenoid. Rated continuous current holds at 63 A through 50 °C ambient; above that it derates stepwise to 56.7 A at 70 °C. That derating curve means you size the breaker for the actual panel ambient, not the nameplate — a 63 A load in a 65 °C enclosure needs the next frame up or active cooling. Three-pole construction, 76.2 mm wide, 130 mm tall, 70 mm deep — standard MCCB footprint for a 3VA frame. ## Integration — panel fit and wiring notes No undervoltage release, no shunt trip, no communication module, no ground fault monitoring on this variant. If you need remote trip or GF protection, you step up to a different 3VA suffix. The TM240 release is fixed thermal and magnetic — no adjustable long-time or short-time pickup, so coordination studies need to account for the fixed curve.","metaTitle":"Siemens 3VA1163-5EF36-0AF0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens 3VA1163-5EF36-0AF0 SENTRON molded case circuit breaker, 3-pole, 63 A, TM240 release, 187 kA at 240 V.
