DC circuit breaker is an electrical device used to protect power equipment, with a wide range of applications, such as railways, subways, urban rail transit, power stations, substations, industrial control, communication equipment, and other fields. Here are some of the main features of this product:

Circuit breaker protection: When a short circuit or overload occurs in the circuit, the DC circuit breaker will automatically trip, cutting off the circuit and providing safety protection.

Overvoltage protection: When an overvoltage occurs in the circuit, the DC circuit breaker can automatically trip to prevent equipment damage.

Overcurrent protection: When the current in the circuit exceeds the rated value, the DC circuit breaker will automatically trip to protect the circuit and equipment.

Mechanical separation function: DC circuit breakers can provide mechanical separation function, facilitating equipment maintenance and repair.

Isolation switch function: DC circuit breakers can provide isolation switch function, which can completely isolate the circuit from the outside, thereby ensuring the safety of personnel and equipment.
