The steep drop at 690 V (3.7 kA) means this is not a 690 V main; it belongs on a 400–500 V motor feeder where the available fault current stays under the curve. ## Motor protection and auxiliary wiring The motor protection design includes phase failure detection, so the breaker trips on loss of one phase — a common failure mode that single-phases a motor and burns the winding. The supplied basic switch is 3VA21635MN320AA0, which is the internal switching mechanism. The 105 mm width is three pole widths at roughly 35 mm per pole — confirm the DIN-rail or mounting-plate layout against the existing breaker cutout. ## Environmental range and storage","metaTitle":"Siemens 3VA2163-5MN32-0JC0 SENTRON MCCB, 63 A, 3-Pole, Motor","metaDescription":"Siemens 3VA2163-5MN32-0JC0 SENTRON molded case circuit breaker, 63 A rated at 40 °C, 3-pole motor protection with phase failure detection.
