The Frontal Electronic Timer, model TEF4-OFF, is designed to provide a compact solution for timing functions. It offers a direct plug-in parallel connection to the coil terminals of AF, AFC contactors or NF, NFC contactor relays.
The timer features a mechanical indicator that shows the state of the contactor and an integrated varistor for surge protection. It is available for control voltages ranging from 24 to 240 V AC/DC.
TEF4-OFF allows time-delayed functions up to 100 seconds in three distinct time ranges, independent of the control system. The timing function is activated by opening the device on which the timer is mounted and operates without additional control supply.
