Uncontrolled DC overload and sudden short-circuit arcs burn storage batteries and PV modules, halting small new energy stations and leading to expensive project compliance fines. The premium YBRM5DC-250 molded case circuit breaker is customized for low-voltage DC loops, delivering reliable electrical safety and full-range circuit protection for loads up to 250A.
This DC-specialized molded case circuit breaker solves the critical arc extinction trouble of direct-current systems. Thermal bimetals avoid unnecessary power cuts under mild long-term overload, while magnetic trip instantly cuts surge currents to eliminate fire hazards. Made of halogen-free flame-retardant casing, it resists dust, moisture and outdoor temperature fluctuation to maintain stable electrical safety all year round, with optional 3P/4P poles and fault alarm accessories for field maintenance.
Perfect for residential energy storage, small photovoltaic plants and industrial DC control cabinets, this compact unit pr…
