Protective devices like Fuses and Circuit Breakers are included to protect against short-circuits
and/or overload currents. The general idea of the fuse is that it melts a conductive link when
current gets higher than its rating and thus stops the current flowing.

If a fuse blows, or if the circuit breaker opens the circuit, it means that a short-circuit and/or
overload situation was present, and a detailed inspection is required to define the condition or
fault which caused the protective device to activate.

The Circuit Breaker is a thermal device used in
the motor distribution system for protecting
against overload and short-circuits in the system.
The circuit breaker has a "switch" on it which
opens once the current exceeds its rating. It has a
time delay effect with brief over-current conditions
(common in motor start up).
Automatic reset circuit breakers will recycle
continuously during an over-current condition.
The composite alloy material will deflect and
separate the contacts when an over-current
situation occurs and return to the run mode as it
cools. The process will continue until the source
of the over-current is removed or corrected.
