Abstract
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.
