Eaton FD90 Soft Start Fire Pump Controller (EPCT Fire)
This controller is quoted to your specifications. Call or Request a Quote Today.
The Eaton FD90 is the soft start model in Eaton's EPCT Fire line of electric fire pump controllers. It's a full-service, reduced-voltage controller that brings the motor up to speed with a smooth, step-less current ramp and slows it down just as smoothly, and it works with standard motors. Every FD90 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 soft start works
The FD90 uses a solid-state starter that provides a step-less, smooth current ramp to the motor. This eliminates current surges and mechanical torque transients at start, which reduces stress on the motor, pump and piping. A soft-stop feature decelerates the motor smoothly as well, which helps reduce water hammer in the system. Other starting options include the FD30 across-the-line, FD40 part winding, FD60 autotransformer, and FD70 and FD80 wye-delta.

FD90 catalog numbers explained
Every EPCT Fire catalog number follows the same pattern. For example, FD90-100-D-L2-E4 is a 100 HP, 480V/60Hz soft start controller with French labels in a NEMA 3 enclosure.
| Segment | Example | Meaning |
|---|---|---|
| Model and starting type | FD90 | FD = stand-alone controller · 90 = soft start |
| Horsepower | 100 | Motor HP, from 5 to 700 HP. Not every HP is available at every voltage. |
| Voltage | D | A = 208V/60Hz · B = 240V/60Hz · C = 380V/50Hz · D = 480V/60Hz · E = 600V/60Hz · F = 415V/50Hz · H = 380V/60Hz · J = 400V/50Hz · K = 400V/60Hz |
| Language | L2 | L1 English · L2 French · L4 Italian · L5 Spanish · L6 Portuguese · L7 Chinese · L8 Polish · L9 Dutch · L11 Turkish |
| Options | E4 | Added codes for enclosures and accessories (see below) |
Common options
| E1 / E2 / E3 / E4 | NEMA 3R / NEMA 4 / NEMA 12 / NEMA 3 enclosure |
| E5 / E9 / E10 | NEMA 4X: 304 stainless / painted steel / 316 stainless |
| F2 | Floor stand, 2 inch height (not available with NEMA 3, 4 or 4X) |
| H / I | High or intermediate withstand rating |
| OP1 – OP4 | Relay board, MODBUS board, secondary 4-20mA device card, alarm board |
| C1 – C5, CX | Extra contacts (pump run, AC power failure, phase reversal, reservoir levels, custom) |
| P7 / P8 | Low suction pressure switch / low suction shutdown |
| R1 – R7 | Space heaters, with thermostat or humidistat options |
| B | Alarm bell |

FD90 or FT90?
The FD90 is a stand-alone controller. If the fire pump also needs automatic transfer to an alternate power source, choose the FT90, which combines the soft start controller and a fire-pump-rated transfer switch in one assembly. You can also pair an FD90 with a separate FPATS stand-alone transfer switch.
