ABB
$90.58
The ABB TEF4-ON is a versatile frontal electronic timer designed to streamline timing functions within electrical cabinets. This compact solution eliminates the need for separate timers by front-mounting directly onto AF, AFC contactors, or NF, NFC contactor relays, ensuring a neat and efficient setup. Featuring a mechanical indicator, it clearly displays the state of the contactor, enhancing operational transparency. The TEF4-ON connects effortlessly via a direct plug-in parallel connection to the coil terminals A1 - A2, simplifying installation and reducing wiring costs. It includes an integrated varistor for built-in surge protection, safeguarding the contactor coil from voltage spikes. With a broad control voltage range of 24 to 240 V AC/DC, the TEF4-ON supports time-delayed functions up to 100 seconds across three distinct time ranges. These ranges are easily selectable via a switch, and the delay can be finely tuned using a rotary switch. The timing function is activated by closing the device on which the timer is mounted, making it a reliable and efficient choice for various industrial applications.
