This MCCB's interrupting rating drops sharply with voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The high values at 240 V through 500 V mean it handles fault currents typical of large transformer-fed panels without cascading upstream. ## Built-in auxiliary switching and trip characteristics The breaker comes with four factory-installed HQ auxiliary switches, giving you status feedback for PLC inputs or alarm panels without adding external contact blocks. The trip time is adjustable between 4 s and 17 s, which suits the starting curve of most induction motors — set it long enough to avoid nuisance tripping during start-up, short enough to clear a locked-rotor fault. The basic switch module is order code 3VA2163-7MN32-0AA0, so if you need a replacement internal switch, that's the spare part number.","metaTitle":"Siemens 3VA2163-7MN32-0AE0 SENTRON MCCB, 63 A, 3-Pole, Motor","metaDescription":"Siemens SENTRON 3VA2163-7MN32-0AE0 molded case circuit breaker, 63 A, 3-pole, motor protection design with phase failure detection.
