PROJOY DC MCCB: Why and How to Apply?

The Necessity of DC MCCB in Energy Storage System

As the core component of the BMS (battery management system) high-voltage box, DC molded case circuit breaker (DC MCCB) plays a vital role in establishing a fine energy storage system, protecting against overload or short circuits, and guaranteeing a stable and reliable operation.

The Necessity of DC MCCB in PV System

DC MCCB is also the key output control device of a combiner box, mainly responsible for the opening and closing functions of the line. It is designed to withstand operating voltages up to DC1500V, making the device ideal for high-voltage DC applications. The high-voltage and high-current design of the circuit breaker can solve the use of more components in series or parallel design, and therefore build a more efficient system.

Why PROJOY DC MCCB?

PROJOY DC MCCB (PEMC Series) is made of DMC plastic material and designed non-polarity. Embedded with functions such as high-quality electrical insulation performance, stronger arc extinguishing ability, higher heat resistance, flame retardant,and stronger corrosion resistance, the series of products can reach up to 1500V, 800A. It can be widely used in industrial and commercial energy storage battery clusters and PV distribution boxes.
