China manufacturers ICHYTI Advanced solar dc mcb Free Sample is a switching device that automatically breaks the circuit. When the current in the circuit exceeds the rated current, solar dc mcb will automatically open the circuit. Its arc extinguishing medium usually uses insulating oil and gas, and has operating characteristics similar to vacuum circuit breakers and sulfur hexafluoride circuit breakers (SF6). solar dc mcb are usually composed of operating mechanisms, arc extinguishing chambers, operating mechanisms, and other components.

ICHYTI solar dc mcb Application

DC circuit breaker is one of the important components in urban rail transit system and electric locomotive. Due to the fact that most of its DC power supply is provided by high-power silicon rectifier devices, the requirements for DC power grid protection components are higher. The DC dedicated circuit breaker with fast response and breaking is one of the key components to ensure the safe and stable operation of rail transit.

In the power system and electric propulsion system of ships, DC circuit breakers are also one of the most important components. It provides fault protection for the power transformation and distribution system and electrical equipment, taking various protective measures to ensure the safe and stable operation of the ship's power supply system and electrical equipment.
