Circuit Breakers and Switches

Check our wide range of electric breakers, circuit breakers and switches designed for routing or interrupting current in the electrical distribution circuit, automatically or manually. Circuit breakers perform 3 key functions: protection, switching, and monitoring. Circuit breakers are designed to “break” (discontinue) the flow of electricity to protect people and equipment when current reaches an unsafe level due to overload, short circuit, or other electrical faults. Schneider Electric Hong Kong is the first choice for all of your circuit breaker and equipment needs. We have the largest selection of circuit breakers in the industry, from the latest NSXm moulded case circuit breaker (MCCB) upto the legendary high current Masterpact air circuit breaker (ACB) range. Our products deliver the reliability and performance in high scale setups like buildings, data centres and shopping centres. They have been trusted by industrial and commercial setups around the world.
