Rated short-circuit breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the steep drop at 690 V means this frame is best applied on 240–500 V systems where fault current headroom is the priority. The 63 A frame with 187 kA at 240 V gives strong series rating potential downstream of a larger upstream device, reducing the need for fully rated breakers throughout the distribution. Maximum power loss is 4 W, negligible for panel thermal budgeting in most enclosures.","metaTitle":"Siemens 3VA2163-5KP42-0AA0 SENTRON MCCB, 63A, 4-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2163-5KP42-0AA0 molded case circuit breaker, 63A rated, 4-pole, 187kA at 240V.
