Why Choose the TEF4-ON [1SBN020112R1000]
The TEF4-ON is a front-mounted electronic timer designed to provide reliable timing functions while optimising cabinet space compared to separate timer units. It securely locks onto AF, AFC contactors or NF, NFC contactor relays, with a mechanical indicator clearly displaying the contactor status. The timer connects directly via a plug-in parallel connection to the contactor coil terminals A1 and A2, simplifying installation. An integrated varistor offers built-in surge protection for the contactor coil, enhancing system reliability. Compatible with a wide control voltage range of 24 to 240 V AC/DC, the TEF4 supports time delays up to 100 seconds across three selectable time ranges. Time settings are easily adjusted using a rotary switch, independent of the control system. Activation occurs automatically when the timer is mounted and the associated device is closed, ensuring precise and dependable timing control in a compact form factor.
