Breaking capacity is the headline number here: 440 kA at 415 V AC and 187 kA at 690 V AC. The 63 A rating holds steady across the full ambient range from 40 °C to 70 °C, so no derating headache in a warm enclosure. It's a line-protection design (not motor-protection), so it's meant for cable and busbar protection in power distribution. The front face carries an IP40 rating — fine inside a closed panel, but don't mount it where washdown water or dust could hit the front. The breaker measures 86 mm deep, 140 mm wide, and 181 mm tall. That 140 mm width across four poles is standard for this frame size — it'll drop into a panel laid out for a SENTRON 3VA2 4-pole MCCB without re-drilling the mounting plate. The depth is shallow enough that it won't crowd the gland plate in a 300 mm deep enclosure.","metaTitle":"Siemens 3VA2163-0KP42-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2163-0KP42-0AA0 molded case circuit breaker. 63 A rated, 4-pole, ETU850 electronic trip unit. 440 kA breaking at 415 V.
