Description
xThe Noark Ex9BP‑JX 4‑pole DC miniature circuit breaker is engineered for reliable protection in high-voltage solar and DC power systems. It safeguards circuits against overloads and short circuits up to 25 A, with a rated operational voltage up to 1000 V DC. Designed for DIN‑rail mounting, it’s compatible with photovoltaic balance‑of‑system (BOS) applications and features thermal‑magnetic tripping characteristics (C‑ and K‑curves). Supported accessories include auxiliary contacts, shunt‑trip, and under‑voltage releases for advanced control.
Key Features
- 4‑pole breaker for comprehensive multi‑string DC protection
- Rated for up to 1000 V DC and 25 A nominal current
- Thermal‑magnetic C‑curve ensures fast tripping on overloads
- High short‑circuit breaking capacity of 10 kA
