The 63 A rating holds steady up to 50 °C ambient; above that it derates gradually to 56.7 A at 70 °C. The TM240 overcurrent release is a thermal-magnetic type — the thermal element handles overloads (adjustable response time up to 1 s), and the magnetic element handles short circuits. No undervoltage release, no shunt trip, no ground-fault monitoring built in; if you need those, you add auxiliary releases externally. Rated insulation voltage is 800 V, so the breaker can be used in 690 V line-to-line systems (the 10.5 kA breaking capacity at 690 V confirms that). The 2 HQ auxiliary switches provide status feedback for remote monitoring or PLC inputs. The 76.2 mm width (roughly 3 inches) fits standard MCCB slots in most distribution boards.","metaTitle":"Siemens SENTRON 3VA1163-3EF36-0AC0 MCCB, 63 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0AC0 molded case circuit breaker, 63 A rated, 3-pole, line protection, breaking capacity 75.6 kA at 240 V.
