## Summary description

Two-pole DC circuit breaker BENY NV822645 rated 40 A and 1000 VDC, designed to protect photovoltaic arrays, battery systems and other DC installations from overloads and short circuits. Compact DIN-rail compatible unit providing reliable manual switching and overcurrent protection for industrial, commercial and residential renewable energy systems and off-grid setups.

## Long description

Two-pole DC circuit breaker BENY NV822645 rated 40 A and 1000 V DC, designed for protection and manual isolation in photovoltaic arrays, battery systems and other DC installations. The compact modular unit mounts on a DIN rail and is intended for use in small PV combiner boxes, DC controllers and similar electrical equipment where fast disconnection and reverse-current protection are required.
Advantages
The breaker features a thermomagnetic trip mechanism, a scientific arc-extinguishing and current-limiting system to quickly interrupt fault currents on the DC side, and a maximum breaking capacity of 1.5 kA. It meets IEC/EN 60947-2 and related standards, provides insulation up to 1500 V DC, and offers mechanical durability of 10,000 cycles and electrical life of 1,000 cycles. The modular white housing and DIN-rail form factor simplify installation and maintenance.
Suitable for
Photovoltaic combiner boxes and PV string protection
DC controllers and power distribution in renewable energy systems
Battery systems and off-grid DC installations
Small commercial and residential DC circuits requiring isolation and overload/short-circuit protection

How to use
Mount the DC circuit breaker on a standard DIN rail inside the electrical enclosure. Connect the DC positive and negative conductors to the two poles according to wiring diagrams and tighten terminals to the recommended torque. Use the breaker for manual switching, isolation and automatic protection against overloads and short circuits in DC circuits up to 1000 V. Verify correct polarity and that cable cross-sections are within the 2.5–25 mm² range before energizing the circuit.
Usage recommendations
Install the breaker in a dry, ventilated enclosure and ensure access for operation and maintenance. Confirm compatibility with system voltage and expected fault current levels; replace the device after it has performed a fault interruption or shows signs of mechanical or electrical wear. Follow local electrical codes and the system manufacturer’s installation instructions.
