3875A-1 Illuminated Push Button Timer  – 3 Wire

The Pushbutton Timer is suitable for retrofit into modern lighting systems. Able to replace existing single gang switches, to provide energy saving functionality by turning off the power source via timer, to avoid unnecessary power usage.The Pushbutton Timer must be used in conjunction activator devices for multi-way applications. This has the ability to latch back on to the mains power supply and reset in the event of a power cut. A Capacitor must be used in the circuit when switching low wattage loads such as fluorescent, compact fluorescent, and LED’s.

Key Features

  • 16A any load type (requires Capacitor PFCC-1 for all types of low wattage loads and in LED lighting)
  • 3 wire (Live, switch live and neutral required)
  • Blue Locator ring• One minute countdown LED indicator
  • Re-set timing sequence at any time during countdown
  • Can be interlinked with any Elkay activator switches
  • Fits into 25mm depth back boxes
  • Time settings from 8 minutes to 8 hours
  • Last minute indicato
  • No Neutral require

Typical applications:

A general purpose timer for use with lighting loads, towel rails, heaters, contactor coils and ventilation loads. Can be retrofitted into any type of circuit with a neutral feed and interlinked with any activator timers to provide multiple switching points. Suitable for all long timing applications such as large occupied areas and battery charging etc.
