Eaton Timer Relay, Screw Terminals, 3A Current Rating - ETR Series - 031884 ETR4-51-A

Switch your appliance at the right moment with this timer relay from Eaton. With its adjustable delay between 3 and 60s, the device blocks current until its system is ready to safely control your circuit. As the component's contacts change over in 50ms, it minimises extra delay for responsive switching. Clip-on rail mounting slots the unit into a cabinet in a snap. Thanks to its 0.5% repetition accuracy, the product precisely times its delay every time for close hardware control. You'll find timer relays like this managing motor starters and packaging systems.

Features & Benefits

• LED indicators for clear power and input status signalling

• Screw terminals keep fingers clear of wiring during connection

• Mechanical lifespan of 30,000,000 operations to ensure long-lasting control

• Handles surge voltages up to 6kV, cutting risk of damage from power faults

How do I adjust the time delay on this timer relay?

You can change this unit's delay by turning its front-mounted screw dial, taking the hassle out of adjusting the relay to fit your system.
