CX-Series Circuit Breaker

CX-Series
Circuit Breaker
Carling Technologies is proud to introduce the CX-Series
circuit breaker, which 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.
Combined, these innovative features make the CX-Series
breaker the best in class, providing stable performance
even in the most demanding applications.
Applications:
ŠŠ Ideal for integration into photovoltaic renewable energy
systems. The CX-Series circuit breaker can be designed
into the system’s combiner box or main disconnect.
ŠŠ Ideal for integration into Information Technologies’ power
distribution equipment utilizing high DC voltage input.
