Breaking capacity reaches 242 kA at 240 V, stepping down to 187 kA at 415/440 V, 121 kA at 500 V, and 3 kA at 690 V. This is a line-protection design (per), not a motor-protection or ground-fault variant. The 86 mm depth is within standard enclosure depth for 3-pole MCCBs in this class — verify gland-plate clearance if back-panel wiring is tight. The auxiliary switch block (2 aux + 1 trip alarm) occupies the right-side accessory slot; wiring exits the breaker face, not the base. ## Power loss and thermal budget Maximum power loss is 7.9 W at rated current. For a 63 A breaker in a sealed enclosure, this is modest — no forced cooling required in most panel layouts, but account for it in the overall thermal budget if the enclosure is densely packed.","metaTitle":"Siemens 3VA2063-6HN32-0BH0 SENTRON MCCB, 63 A, 3-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2063-6HN32-0BH0 molded case circuit breaker, 63 A continuous, 3-pole, 242 kA breaking at 240 V.
