CX-Series Circuit Breaker


Carling Technologies introduces the CX-Series circuit breaker, offering features that provide stable performance even in the most demanding applications


Carling Technologies CX-Series circuit breaker features a unique and innovative patent-pending arc quenching configuration that allows the breaker to safely handle high amperage and high DC voltage applications in a compact package. By using a patent-pending magnetic flux boosting terminal configuration, a strong magnetic field is created thus motivating the arc into an enhanced arc chamber improving the breaker’s overall performance and reliability.

The permanent magnets located at the entrance of the arc chamber combined with the upper and lower arc runner increase the magnetic blow out force and aid in motivating the arc off of the contacts and into the arc chamber.

An enhanced arc chamber features arc splitter retainers with integrated pressurizing walls, which facilitates heat transfer from the arc thereby providing additional cooling and quick transition into the magnetically induced splitter plates. In turn, the twelve (12) splitter plates attract, segment and cool the arc for full extinction.
