The 3-pole construction handles three-phase systems, and the breaking capacity at 240 V hits 330 kA — that's high enough for most industrial service-entrance or sub-distribution applications where fault current is substantial. ## Breaking capacity across voltage levels This MCCB's interrupting rating varies with system voltage: 330 kA at 240 V, 242 kA at both 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V tells you this is a 500 V-class frame — if your system runs 690 V, the 3.7 kA limit may be tight for high-fault installations. For standard 480 V or 600 V class panels, the 187 kA at 500 V gives comfortable margin. The 3VA2163-7HN32-0AC0 measures 105 mm wide, 181 mm tall, and 86 mm deep. The 86 mm depth means it clears shallow enclosures where deeper frames would hit the backplate or door.","metaTitle":"Siemens 3VA2163-7HN32-0AC0 SENTRON MCCB, 63 A, 3-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2163-7HN32-0AC0 molded case circuit breaker, 63 A continuous, 3-pole, 330 kA at 240 V.
