643A-H5
Application of power simultaneously initiates timing of the preset interval and turns ON the load. At the end of the timed period the timer’s switch opens , turning the load OFF. Power to the timer must be applied continuously throughout the timing period. Removal of power causes the timer to reset. The next cycle can then be initiated by application of power.

Control the timing of high power electric heaters, motors, lamps, transformers and other high current loads rated less than 15 amps (150 amps inrush). CMOS digital circuitry is combined with a high current solid state switch. P/C board and internal components are encapsulated in a flame retardant molded housing, fitted with quick connect wiring terminals. Available in all standard voltages and frequencies. Fixed or adjustable timing from 0.1 seconds to 24 hours.
