At 415/440 V the 187 kA rating still exceeds what most distribution transformers behind a typical 2000 kVA unit can deliver, so selectivity with downstream breakers is achievable without oversizing the main. Dimensions are 181 mm height, 105 mm width, 86 mm depth — a standard SENTRON 3VA2 frame footprint. The 105 mm width across three poles matches the typical 35 mm per-pole spacing on DIN-rail or backplate layouts. Maximum power loss is 5.4 W, so no forced cooling is required in a standard IP30 enclosure but adjacent devices should not be thermally blanketed.","metaTitle":"Siemens 3VA2063-6HL32-0KH0 SENTRON MCCB, 63 A, 242 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-6HL32-0KH0 molded case circuit breaker, 3-pole, 63 A rated continuous current, 242 kA breaking capacity at 240 V.
