1p 16A 20A 40A 63A DC MCB 250V Circuit Breaker for PV System C Curve Battery Main Switch

A DC circuit breaker is a device that is used to interrupt the flow of current in a direct current (DC) electrical circuit. It is designed to protect electrical devices and systems from damage caused by overcurrent, short circuit, and ground fault conditions.

A DC circuit breaker consists of a pair of contacts that are connected to a switching mechanism. When the circuit breaker is in the "on" position, the contacts are closed and current is allowed to flow through the circuit. When the circuit breaker is in the "off" position, the contacts are open and the flow of current is interrupted.

DC circuit breakers can be used in a variety of applications, including in batteries, solar panels, and other renewable energy systems. They are typically rated for a specific current and voltage range, and are available in a variety of sizes and configurations to meet the needs of different electrical systems.

DC circuit breakers are typically used in low-voltage systems, where the voltage is below 600 volts. In higher-voltage systems, AC circuit breakers are generally used.
