The 3VA2563-5HR32-0AA0 is a 3-pole IEC frame 1000 molded-case circuit breaker with a 55 kA interrupting capacity at 415 V AC — class M breaking capacity, meaning it handles medium-level fault currents typical in industrial distribution panels without needing a current-limiting upstream device. The ETU345 electronic trip unit provides LI (long-time and instantaneous) protection: the long-time pickup Ir is adjustable from 250 A to 630 A, and the instantaneous pickup Ii is fixed at 12 x In (12 x 630 A = 7560 A). This breaker ships without overload protection (the LI curve covers short-circuit and overload via the adjustable Ir, but there is no separate thermal overload relay). The busbar connection means it bolts directly onto a busbar system, common in switchgear assemblies.
Deployment context
Mounts in a standard IEC switchgear panel via busbar connection — no DIN-rail adapter needed. The 3-pole design suits three-phase distribution feeders, motor control center (MCC) incoming sections, or transformer secondary protection. The 55 kA @ 415 V rating provides adequate SCCR for most industrial plant-floor distribution without requiring a current-limiting fuse upstream.
