LDB-3 Delay On Break Timer Relay

  • Delay On Break
  • 24VAC low voltage control
  • Solid state output – 1A max.
  • Protects compressors against premature cycling
  • Fixed time delay – 3m
  • LED Indication (Power and Output)
  • 17.5mm wide, DIN Rail mount

Designed to protects compressors in refrigeration, air conditioning and heat pumps against premature cycling by preventing restarting until time delay “lockout” period has completed. The timer is fixed with a 3 minute delay period. LED indication is provided giving the user clear status information about the supply and switching output.

 

  • Timing function: Delay On Break
  • Supply voltage:  24VAC +/-25%
  • Time delay: 3m (fixed)
  • Output: Solid state 0.04 – 1A
  • Dimensions(mm): W:17.5 x H:89 x D:66.5

Typical applications include:

  • Refrigeration compressor controls
  • Air conditioning systems
  • Heat pump systems
  • Thermostat-controlled compressor panels

Key benefits:

  • Helps reduce premature compressor cycling — A fixed three-minute lockout prevents the compressor control load from re-energising immediately after power is removed.
  • Maintains the restart delay after power returns — Reapplying power before the lockout expires does not permit the output load to energise until the remaining delay has finished.
  • Makes control status visible — Separate LEDs indicate supply condition and output or timing state, helping users check whether the circuit is waiting or active.
  • Simplifies low-voltage control integration — The 24VAC solid-state output supports suitable compressor control loads and the unit can work with anticipator thermostats.
