Interrupting capacity is the headline number here: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and still 52.5 kA at 690 V. ## Panel fit and footprint The 3VA2063-8JP42-0AA0 measures 140 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA frame size that drops into existing panel layouts without re-drilling. Front IP40 protection means it's suited for enclosed distribution boards where splash or tool ingress is minimal.","metaTitle":"Siemens 3VA2063-8JP42-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2063-8JP42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, ETU550 electronic trip unit.
