Frequently Asked Questions

Explore FAQ >

What is a DC MCCB (Molded Case Circuit Breaker)?

A DC MCCB (Molded Case Circuit Breaker) is a protection device designed for DC circuits. It automatically disconnects the current in the event of overloads or short circuits, preventing equipment damage and safety hazards such as fires.

Why do solar photovoltaic systems need a DC MCCB?

Solar photovoltaic systems use DC electricity, and DC MCCBs are specifically designed for these types of circuits. They provide reliable protection against overloads and short circuits, ensuring the system can quickly cut off power in case of faults, safeguarding the equipment and ensuring smooth operation.

How do I choose the right DC MCCB?

When selecting a DC MCCB, consider the following factors: Rated Voltage and Current: Ensure the MCCB's ratings are higher than the system's maximum operating voltage and current. Breaking Capacity: Choose a breaker with a sufficient breaking capacity to handle potential short-circuit currents. Environmental Conditions: Consider the temperature, humidity, and other environmental factors where the breaker will be installed. Certification Standards: Ensure the MCCB meets relevant safety certification standards, such as IEC, UL, etc.

How do I correctly install a DC MCCB?

To install a DC MCCB, follow these steps: Disconnect the Power: Ensure the system power is completely turned off before starting the installation. Identify Terminals: Correctly identify the input (positive) and output (negative) terminals of the MCCB. Proper Wiring: Follow the wiring diagram in the product manual to connect the MCCB correctly. Regular Inspections: Periodically check the connections to ensure they are secure and the system is operating safely.
