At 55 °C it still carries 60.48 A, and at 70 °C it holds 56.7 A, so it's built for warm cabinets without stepping up a frame size. ## Interrupting capacity by voltage This MCCB delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. ## Thermal-magnetic release and auxiliary contacts That makes it a straightforward line-protection breaker: thermal element handles overloads, magnetic coil handles short circuits. It comes with four HQ auxiliary switches built in, so you get status feedback without bolting on an external block. The 3VA1163-4EF32-0AE0 measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.","metaTitle":"Siemens 3VA1163-4EF32-0AE0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens 3VA1163-4EF32-0AE0 SENTRON molded case circuit breaker. 63 A continuous, 121 kA interrupting at 240 V.
