Meterk 12 V 100 A 4-Terminal Solenoid Relay 391-2-C

SKU CH-HFQP-ZHRGQ

12 V 100 A four-terminal solenoid relay replaces Prestolite, Monarch and PJ dump-trailer OEM parts for hydraulic dump and leveling-jack circuits

  • Compatibility/FitmentOut-Opening, Narrow Stile, Store Front Doors
  • 12 V 100 A continuous rating powers hydraulic dump trailers reliably
  • 200 A intermittent surge handles peak loads during energised or de-energised operation
  • 4-terminal design fits Prestolite SAZ-4201GJ Monarch Bucher 07522 and PJ KTI 190107 systems directly
  • 180 °C copper coil windings resist heat dust liquids rust and corrosion in harsh environments
  • High-strength metal body with corrosion-resistant coating ensures durable OEM replacement for dump pumps and RV leveling jacks

What This Solenoid Does

This Meterk 12 V 100 A 4-terminal solenoid relay switches high-current loads on hydraulic dump trailers and RV leveling jacks. It is built for intermittent duty with a 200 A surge rating and uses 180 °C copper wire in a corrosion-resistant housing. The unit is a direct OEM replacement for Prestolite, Monarch/Bucher and IRON BULL hydraulic power units.

When to Replace the Original

Fit this relay when the factory solenoid on a dump trailer pump or hydraulic jack fails to engage or overheats during intermittent operation. The jump is worth it if the original part number matches SAZ-4201GJ, 7522, 07522, 190107, 070009 or 391-2-C and the system runs on 12 V DC with a 100 A continuous draw.

What to Verify Before Ordering

Confirm that your equipment uses a 4-terminal 12 V solenoid rated for 100 A continuous and 200 A intermittent surge. Check that the mounting pattern and terminal layout match the original Prestolite or Monarch/Bucher unit. This relay is not for applications requiring a different terminal count, voltage or continuous current rating.

Questions about this item

What terminal count and voltage does the 391-2-C solenoid use for mounting?

The 391-2-C is a 4-terminal 12 V solenoid designed as a direct OEM replacement for hydraulic dump trailers and leveling jacks.

How is the 391-2-C installed and what wiring step is often missed?

Mount the solenoid in the original bracket, connect the two large power terminals to battery and load, then attach the two small coil terminals to the control circuit — forgetting either coil wire leaves the relay dead.

When should the 391-2-C be replaced based on its duty rating?

Rated for 100 A continuous and 200 A intermittent surge with a 180 °C coil, replace it if the contacts stick, voltage drop climbs, or the coil overheats during repeated dump cycles.
