Eaton FD40 Part Winding Fire Pump Controller (EPCT Fire)

This controller is quoted to your specifications. Call or Request a Quote Today.

The Eaton FD40 is the part-winding model in Eaton's EPCT Fire line of electric fire pump controllers. It's a full-service, reduced-voltage controller for electric fire pumps driven by part-winding motors. Every FD40 is built to order, so we quote each one to your motor, voltage, enclosure and options. Call (786) 336-5783 or send us your catalog number or spec section.

How part-winding starting works

A part-winding controller starts the motor on part of its windings, then connects the rest once the motor accelerates. This reduces starting current by up to 40% while maintaining up to 50% of motor starting torque. The FD40 is the most economical method of reduced-voltage starting, but it requires a special motor wound for part-winding starting. If your motor isn't wound for part-winding, consider the FD60 autotransformer, FD70 or FD80 wye-delta, or the FD90 soft start. Where full-voltage starting is acceptable, see the FD30 across-the-line controller.

EPCT Fire features

  • Event history: logs up to 65,000 time-stamped events, with on-screen filtering for troubleshooting
  • Programmable output relays for common alarm, power/phase failure, phase reversal and pump run
  • Optional boards:
    • Relay board: four (4) one form-C programmable output relays
    • MODBUS board: output communication via RS422 or RS485
    • Secondary 4-20mA device board: additional connections for external pressure transducers, temperature sensors and similar devices
    • Alarm board: a supervisory powered alarm output
  • Enclosures: UL Type 2 (drip-proof) standard; Type 3, 3R, 4, 4X and 12 available
  • Standards: built to NFPA 20 and listed to UL 218. See the bid submittal for the full list of approvals.

FD40 catalog numbers explained

Every EPCT Fire catalog number follows the same pattern. For example, FD40-100-D-L1 is a 100 HP, 480V/60Hz part-winding controller with English labels in the standard enclosure.

Segment Example Meaning
Model and starting type FD40 FD = stand-alone controller · 40 = part winding

FD40 or FT40?

The FD40 is a stand-alone controller. If the fire pump also needs automatic transfer to an alternate power source, choose the FT40, which combines the part-winding controller and a fire-pump-rated transfer switch in one assembly. You can also pair an FD40 with a separate FPATS stand-alone transfer switch.

What we need for a quote

  • Motor horsepower, and confirmation the motor is wound for part-winding starting
  • Line voltage, phase and frequency
  • Enclosure type
  • Options and label language
  • Withstand rating, if your project requires high or intermediate
