CX-Series
CX-Series
CIRCUIT BREAKER
The CX-Series circuit breaker features a unique and innovative 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
Combined, these innovative features make the CX-Series breaker the best in class, providing stable performance
even in the most demanding applications.
