Features 1、FUNCTION: Photovoltaic circuit breakers are used to defend distribution facilities from overload and short circuit damage, and can also be used for control and isolation. 2、QUICK RELEASE: The electromagnetic release system in the circuit breaker can immediately release in case of a short circuit, protecting the circuit safety. 3、ARC EXTINGUISHING: DC arc extinguishing is more difficult than AC arc extinguishing. The DC circuit breaker has a magnetic system that helps in arc extinguishing. 4、APPLICATION: DC photovoltaic circuit breakers are used in DC power systems, ship power systems, solar photovoltaic systems, or other DC systems. 5、INSTALLATION: Modular structure, screw clamp wire, 35mm DIN rail installation. PA66 material is flame retardant and fireproof, providing the circuit breaker with a long service life.
