The CX-Series circuit breaker features an innovative configuration that allows the breaker to safely handle high amperage and high DC voltage applications in a compact package.

By using a magnetic flux boosting terminal configuration, a strong magnetic field is created thus motivating the arc into an enhanced arc chamber.

Permanent magnets 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.

The arc chamber features arc splitter retainers with integrated pressurizing walls, which facilitates heat transfer from the arc 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.

Perfect fit for 380VDC Applications.
UL 489 Listed and ideal for integration into PDUs utilizing high DC voltage input.
