The Solar PV DC Circuit Breaker series provides reliable overcurrent protection for solar energy systems and battery storage applications. These breakers are specifically designed for direct current (DC) control circuits in photovoltaic installations.
Key features include 1P and 2P configurations with rated currents from 63A to 250A, suitable for various system requirements. The breakers offer both B and C curve types for different protection characteristics, with a high breaking capacity of 6kA/10kA to ensure system safety.
These devices provide comprehensive protection against overload and short circuit conditions. The clear ON-OFF position indicator allows for easy status monitoring, while the DIN rail mounting (35mm) ensures quick and secure installation in electrical panels.
For enhanced system protection, we recommend installing appropriate surge protection devices upstream of the circuit breakers. The units automatically disconnect the circuit when earth faults or leakage currents exceed rated values, providing additional safety.
The breakers support both terminal and pin/fork type busbar connections, offering flexibility in system wiring. Their maintenance-free design makes them suitable for use by non-professional operators in solar energy applications.
With certifications including CE, CB, and SAA, these DC circuit breakers meet international safety standards for photovoltaic system applications. The air arc-extinguishing medium ensures reliable operation under various load conditions.
