Breaking capacity runs from 440 kA at 240 V down to 53 kA at 690 V, so this breaker handles high-fault utility feeds at lower voltages while still clearing faults on 690 V industrial buswork. That depth — 86 mm — is the dimension you check against gland-plate clearance and door-swing arc.","metaTitle":"Siemens 3VA2063-8JQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU56","metaDescription":"Siemens SENTRON 3VA2063-8JQ46-0AA0 molded case circuit breaker, 63 A rated, 4-pole, ETU560 release.
