Noark PV DC Circuit Breaker 63A 4P 1000V

4-pole DC miniature circuit breaker — isolates four DC conductors simultaneously

Rated current: 63 A — suitable for higher-current DC string or battery circuits

Rated voltage: 1000 V DC in 4P mode — supports high-voltage PV installations

DIN-rail mounting — modular and eases panel mounting and wiring

Tripping curve options: C / K magnetic characteristic — flexibility for differing loads / fault behaviors

Designed for DC circuit protection — optimized for non-AC operation, avoiding AC-only limitations

Robust construction with good breaking capacity (e.g. ~ 6 kA) under DC conditions

Accessory integration — supports auxiliary contacts, shunt trips, under-voltage releases

Non-polarized design (some models) — safer installation with less chance of wiring error
