Pluggable Circuit Breaker Package

       Disclosed is a design for a pluggable circuit breaker
assembly which insures that the circuit breaker is in the off
position when it is either plugged or unplugged.

      Concurrent maintenance is becoming a necessity in many areas of
new machines.  Currently there are a few manufacturers that make
pluggable circuit breakers to ease replacement in the field.  For
concurrent maintenance, the circuit breaker must be open when
plugging or unplugging.  If the circuit breaker is closed, it will
draw an arc between the mating contacts which could damage or degrade
the performance of the contacts.  Providing a circuit breaker
assembly that insures the circuit breaker is in the off position
during plugging and unplugging protects the contacts of the pluggable
circuit breaker.

      The drawing shows the circuit breaker module and cage assembly.
The circuit breaker module is made up of the circuit breaker, circuit
breaker housing and pin contacts.

      As the circuit breaker module is inserted into the cage, the
actuator arm is pressed down, turning off the circuit breaker.  When
the circuit breaker module is fully inserted into the cage, the
actuator arm springs upwards, latching the module into the cage.

      To remove the circuit breaker module, the actuator arm must be
pressed down far enough to clear the circuit breaker module cage,
thus turning off the circuit breaker.
