Electronic timers

TEF3 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
1SBC101337F0010 TEF3 electronic timers are front-mounted and locked on AS/ASL contactors or NS/NSL contactor
relays. A mechanical indicator allows to show the state of the contactor.
Safe and cost-reduced wiring
TEF3-ON
TEF3 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
TEF3-ON or TEF3-OFF allow time-delayed functions up to 100 s in 3 distinct time ranges, 05
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.
