NDC Circuit Breaker at the Heart of Lightning DC

The patented arc transfer system prevents internal contamination of the circuit breaker compartment and cubicle.

The Cold Cathode Arc Chute Assembly dissipates all arcs whilst the transfer coil provides additional magnetic flux across the contact gap, assisting with the interruption of low currents that would otherwise lead to long arcing times.

The Magnetic Actuator is based on a solenoid plunger, and provides the motion required to close the main contacts and to reset the latch device on tripping.
