The Renogy DC Circuit Breaker Box is an indoor-rated enclosure that offers centralized installation and protection for devices in the residential and commercial solar system. For solar energy systems, we suggest combining two 1P miniature circuit breakers, one 2P molded case circuit breaker, one 2P surge protection device, and one 2P ground fault circuit breaker to provide comprehensive protection and disconnection methods for the system. The built-in DIN rail enables easy installation of the protection devices.
Realizing the disconnection of different devices in the solar energy system. Each pair of devices will be equipped with a circuit breaker to realize the system's section management and comprehensive protection.
When the equipment needs maintenance or inspection, the relevant circuit can be disconnected to ensure safety.
Surge protection devices and ground fault protection devices can be installed to protect equipment from lightning protection and ground faults.
For solar panel system, we suggest the following combination:
two 1P miniature circuit breakers
one 2P molded case circuit breaker
one 2P surge protection device
one 2P ground fault circuit interrupter
Please note all the breakers, interrupter and surge protection device are not included.
The box is made of cold-formed steel which is durable and resistant to corrosion. Built-in Copper Busbars have good electrical conductivity to ensure the stable operation of the system.
Material and workmanship warranty for 1 year.
The diagram detailed shows all components of the box, besides these, waterproof strain reliefs or conduits are reserved for installation.
The product offers a built-in standard DIN rail for easy installation. Mounting holes are reserved on the back for fixationto make sure the box is firm and stable.
When you lock the door, screw the black ring first and then lock it with the key. When you open it, use the key first, and then twist the black ring.
