Protecting low-voltage circuits
1-1 Description
1-1 Description
The most common faults occurring with low-voltage circuits
are overcurrent (resulting from overload or short-circuit),
ground faults, and phase-loss. A device that will protect
equipment from these faults is therefore needed for reliable
and economical operation. The following section describes
lowvoltage circuit faults along with measures to protect against
them.
