Macromatic Over Temperature & Seal Leak Relay Competitive Comparison

SUBMERSIBLE PUMP PROTECTION

Macromatic Over Temperature & Seal Leak Relay Comparison

Compare Macromatic TCF, TCF-E and TCF-F relays with MPE PMR Series and Flygt MiniCAS pump monitoring relays. Macromatic combines temperature and seal leakage monitoring with dual-color status LEDs and a compact housing for inner-door mounting in pump control panels.

0.485" less depth

3.125" versus 3.61" behind the flange: approximately 13% less depth than other manufacturers for a lower profile

Clear status at a glance

Two green/red LEDs distinguish normal operation from temperature or seal leakage alarms.

UL Listed with socket

Use the appropriate relay and socket combination to meet the listed assembly requirements.

Specifications may apply specific series. Contact ratings have different voltage and load conditions, and should not be compared by amperage alone. Verify the exact wiring diagram, socket, and mounting drawing on the product page before selecting a replacement.

Choose by pump sensor type

TCF - resistance sensing: Choose the sensitivity range required by the pump's seal leak probe. The 4.7–100 kΩ and 1–250 kΩ options are model dependent.

TCF-E - float-type leakage detection: Designed for pumps using a float-type leakage detector, including compatible Ebara applications.

TCF-F - FLS or CLS leakage sensors: Designed for compatible Flygt submersible pump monitoring applications. Confirm sensor compatibility when evaluating a MiniCAS or PMR2 replacement.

Before replacing a pump monitoring relay

  • Match the sensor: Identify resistance, float, FLS or CLS detection before choosing a series.
  • Confirm power and outputs: Check the control supply, contact arrangement and connected load.
  • Check panel fit: Measure the cutout, mounting holes and available depth, including wiring clearance.
  • Select reset behavior: Confirm whether the application requires automatic or manual over temperature reset.

Check the cutout, even when flange sizes match

The flange dimensions shown are identical, but the specified panel cutouts differ. Confirm the installation drawing and existing opening before planning a replacement.
