Abstract: A current overload protection device adapted for use in a system sequentially connecting a plurality of selected loads to a common source of excitation, said protection device opening the common circuit during those times when a shorted load is on the circuit. In order to provide indication subsequent to the selection of the shorted load, the device includes a latching relay activating an alarm which will therefore stay on after other properly operating loads are selected. The device comprises a current protecting relay having the coil thereof connected in series with a triac, and a current sensing resistor connected in series with one of the switches of the protection relay forming a circuit across the triac and the coil series. One other switch of the protecting relay, when pulled in, completes the circuit to the latching relay which energizes an alarm.
