Catalog No. : 1SBN020114R1000

Description:  TEF4-OFF Frontal Electronic Timer

UPC: 3471523130654

TEF4 frontal electronic timers are used for realizing timing function and are available in ON-delay and OFF-delay versions. Compact solution in cabinet compared to separate timers TEF4 electronic timers are front-mounted and locked on AF contactors or NF contactor relays. A mechanical indicator allows to show the state of the contactor. Safe and cost-reduced wiring. TEF4 electronic timers are supplied by a direct plug-in parallel connection to the coil terminals A1 - A2 of the contactor or contactor relay. A varistor is integrated on the timer to offer a built-in protection against surges in the contactor coil. Available for a wide control voltage range 24...240 V AC/DC TEF4-ON or TEF4-OFF allow time-delayed functions up to 100 s in 3 distinct time ranges, independently of the control system. The time delay ranges are selected by a switch and the time delay can be adjusted by means of a rotary switch. The timing function is activated by closing or opening the device on which the timer is mounted. The OFF-delay version operates without additional control supply.
