An over-current control device, either single or three phased, is provided
for protecting equipment and persons under fault conditions. The control
device incorporates integrated circuitry to provide over-current
protection to monitored circuits/components. The preferred embodiments of
the device include time/current characteristic circuitry and trip
circuitry to cause the contacts of a relay to transition, thereby
actuating a magnetic latch and providing either direct or indirect
over-current control.
