ABB TEF5 ON – 1SBN020312R1000

• Product Name : Contactor
• Type : Electronic Timer

The TEF5-ON is a front-mounted electronic timer designed to provide a compact timing solution within control cabinets, eliminating the need for separate timers. It is compatible with UA16 to UA75, AX contactors, and NX contactor relays, securely locking in place for easy integration. A mechanical indicator displays the contactor’s status, while a direct plug-in parallel connection to the coil terminals A1 – A2 ensures seamless operation. The timer features an integrated varistor for built-in surge protection in the contactor coil. Supporting a wide control voltage range of 24…240V AC/DC, the TEF5 allows for time-delayed functions of up to 100 seconds across three distinct time ranges, adjustable via a rotary switch. The ON-delay function is activated when the device it is mounted on is closed.
