High Speed DC Circuit Breaker

A high-speed DC circuit breaker is an uncomplicated device that is designed to protect specific electrical appliances. They are specifically designed for overload and short-circuit currents.

When the set upper limit of current flow is reached, the high-speed DC circuit breaker trips. This happens within a given duration of time to break the circuit and protect the electrical appliance from being damaged.

Key Features

One of the key features of a high-speed DC circuit breaker is a high insulation voltage. Also, it offers a good interruption performance with a lightweight and compact design.

Another important feature is the high-rated capacity for short-circuit breaking and making.

The maintenance process is also simple and easy because of its simple and reliable structure with a durable holding type.

A high-speed DC circuit breaker has a high operational frequency.

In addition to the above, depending on your needs, it also comes with a control module for holding and closing sequences.

Applications

High-speed DC circuit breakers are mainly used within the transportation industry. Any transportation system that uses a DC traction requires a high-speed DC circuit breaker. History has it that these devices were originally designed for rail services.

However, other sectors within the transportation industry have also adopted these devices. For instance, vehicles with DC traction systems require this type of circuit breaker.

Other industries such as mining and marine also require high-speed DC circuit breakers for their operations.
