For a 63 A frame, the 242 kA at 415 V gives solid fault-clearing headroom on most industrial 400 V distribution boards — you can coordinate downstream without worrying about cascading failures on a bolted fault. That 86 mm depth is the can body — it fits standard SENTRON panel cutouts and leaves room for the shunt trip wiring behind the DIN rail adapter plate. No communication module or aux switch on this variant, so the wiring gland stays clean. ## Thermal performance and ambient derating The breaker is rated for operation between -25 °C and 70 °C, with storage down to -40 °C. Maximum power dissipation is 4 W, negligible for panel heat budget.","metaTitle":"Siemens 3VA2163-7MS32-0KA0 SENTRON MCCB, 63 A, 3-Pole, Shunt","metaDescription":"Siemens 3VA2163-7MS32-0KA0 SENTRON molded case circuit breaker, 63 A rated at 40°C, 3-pole, 330 kA at 240 V breaking capacity.
