Load Controls PFR-1550 Single Set Point, Fast Response Compact Digital Load Control
Use the fast response compact digital load controls to protect valuable equipment from damage from problems such as overloads, jams, obstructions, sudden load change, loss of load, missing tools, and misplaced parts.
Mounting: Wiring is done to unpluggable terminal strips on the rear of the unit.
Three ways to mount
- On door or raceway - use cutout template
- Panel Mount - use template + Optional Bezel Kit
- On Wall - Use standard outdoor junction box + Optional Outlet Box Adapter
Voltage - 120 volts AC is taken from two of the phases. If the motor starter already has a 120-volt control transformer with 10VA of free capacity, it can be used. Otherwise, install a separate transformer. It is okay if the secondary is grounded. Be sure to note which two phases supply the transformer.
Features:
- Single Set Point Load Control
- High Trip or Low Trip Selectable
- Power Sensing for Highest Sensitivity
- Overload or Loss of Load

Load Controls PFR-1550 Single Set Point, Fast Response Compact Digital Load Control monitors the true power (overload or loss of load) going to a motor. By sensing power (volts x amps x power factor) rather than just amps, there is much greater sensitivity. The compact digital control has a fast response time that is 10 times faster than typical controls. The rugged enclosure is designed to fit in many places and protects your valuable equipment from problems and damages. Specify Outlet Box Kit for Wall Mount or Bezel Kit for Panel Mount if needed.
It has one adjustable trip point which can be either:
- High - Relay switches when load is above the trip point
- Low - Relay switches when load is below the trip point
