Delay-on-Make/Delay-on-Break

Littelfuse delivers vital products to address customer needs for protecting and safely controlling electrical power. Our single-function & control relays product portfolio includes 2 series of delay-on-make/delay-on-break time-delay relays that work in ac and dc systems. Each version boasts excellent repeat accuracy. These relays can be used to start a motor when a button is pushed and allow the motor to operate for a set period of time. Available features include microcontroller-based circuitry, solid-state components, encapsulation, and LED indicators.
  • Ac input voltages from 24 V ac to 230 V ac
  • Dc input voltages from 12 V dc to 48 V dc
  • Fixed or selectable time delays from 1.5 s to 1230 s
  • Repeat accuracy as high as ±0.1 % or 20 ms, whichever is greater
  • Operate at temperatures up to +85 °C
  • Reset times ≤ 150 ms
  • Initiate times ≤ 40 ms
  • Time delays vs. temp. & voltage ≤ ±2 %
