What is a high voltage circuit breaker?

A high voltage circuit breaker is an electrical device designed to protect high voltage power systems by interrupting the flow of electricity during fault conditions, such as short circuits or overloads. It operates by detecting abnormal current levels and quickly opening the circuit to prevent damage to equipment and ensure safety.

What are the different types of high voltage breakers?

Read how we're working together with eleven other partners from nine countries to achieve this. We classify our high voltage breakers primarily into: live tanks and disconnecting circuit breakers (DCBs); and dead tanks and dead tank compact (DTC). Both categories include Blue products which use zero F-gases.
