Small black cylindrical 12V relay with three metal terminals and mounting bracket

Meterk 5243#HI 200A 12V 3 Terminal Solenoid Relay

SKU CH-T7JH-TQPD6

A 12 VDC, three-terminal solenoid relay rated for 200 A maximum transient current and 80 A continuous duty with 14 Ω coil resistance

  • Compatibility/FitmentOut-Opening, Narrow Stile, Store Front Doors
  • Handles 200 A peak current for heavy-duty starting
  • Continuous 80 A rating suits sustained winch or cart loads
  • 12 VDC coil with 14 Ω resistance draws only 10.2 W
  • Nickel-plated 180 copper windings resist corrosion for longer service life
  • Direct OE replacement for Trombetta 974121501109 and listed part numbers

Application Fit

This Meterk 5243#HI solenoid relay is built for 12 VDC systems on marine craft, winches, golf carts, hydraulic units and factory machines. It suits installations that need a three-terminal, surface-mount relay with automatic operation and a normally-open contact. It is not for buyers who need a different coil voltage, a different terminal count or a latching contact mode.

Critical Specification

The coil runs on 12 Volts with 14 Ohms resistance and draws 10.2 watts. The contact is rated for 200 Amps maximum transient current, while the manufacturer recommends keeping continuous current below 80 Amps. Selecting this part hinges on matching those exact electrical limits to the circuit you are controlling.

Thermals and Power

In normal use the coil dissipates 10.2 watts at 12 VDC, a modest load that typically stays cool without forced airflow. The copper windings and nickel-plated surfaces resist corrosion, helping maintain stable resistance and low contact heating during repeated switching cycles. No active cooling is required for typical duty cycles.

Highlights

Questions about this item

What does the 200 A rating mean once the relay is installed?

The 200 A figure is the maximum transient flash current. The manufacturer recommends keeping continuous working current below 80 A for reliable operation.

What does the 12 V coil voltage cap in practice?

The coil operates at 12 VDC with 14 Ω resistance, drawing about 10.2 W. It will not switch if the control voltage falls significantly below 12 V.

How does the three-terminal layout affect mounting?

The relay uses a surface-mount design with three terminals for power in, power out, and coil control. It fits the same footprint as the listed Trombetta and OE part numbers.
