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.
Additional Features:
• Temperature stable hydraulic/magnetic
overcurrent sensing technology.
• Optional relay trip circuit permitting remote
operator system shut down.
• Choice of 6-32 or M3 mounting inserts
providing secure panel mount installation.
• Choice of handle colors and legends, consult
factory for details.
Applications:
• 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.
• Ideal for integration into Information
Technologies’ power distribution equipment
utilizing high DC voltage input.
