Value Brand Electric Sequencer 1 Switch 1-25 Sec

SKU CH-T13S-76330

Controls HVAC and refrigeration systems with a single switch adjustable from 1 to 25 seconds off-delay

  • Adjustable timing from 1 to 25 seconds for flexible control
  • Handles up to 10 amps at 120V AC for reliable switching
  • Supports 7 amps at 240V AC for higher voltage systems
  • Manages 72 amp locked rotor current at 120V AC for motor starts
  • Operates in horizontal or vertical orientation for versatile installation

Application and purpose

This electric sequencer controls the staged start-up of HVAC and refrigeration systems. It provides a single switching stage with an adjustable off-delay between one and 25 seconds. Installers use it to prevent compressor short-cycling and reduce inrush current on residential or light-commercial equipment.

Timing range

The auxiliary switch off-delay adjusts from one second minimum to 25 seconds maximum, while the on-delay spans 65 to 115 seconds. Selecting the correct off-delay within this window determines whether the sequencer matches the equipment manufacturer's required delay specification.

Electrical capacity

Rated for 10 amps full-load at 120 volts AC and seven amps at 240 volts AC, with locked-rotor ratings of 72 and 42 amps respectively. It comfortably handles typical single-phase compressor and fan motors but is not sized for larger three-phase loads or higher current applications.

Questions about this item

What does the 1-25 second off-time range mean for my HVAC system?

The auxiliary switch can delay its off cycle anywhere from 1 second up to 25 seconds, letting you stagger compressor or fan shutdown.

How do the 120 V and 240 V ratings limit the loads I can connect?

At 120 V the sequencer handles 10 A full-load and 72 A locked-rotor; at 240 V it handles 7 A full-load and 42 A locked-rotor.

Can I mount this sequencer vertically or must it be horizontal?

The unit is approved for both horizontal and vertical installation orientations.
