Eaton FH27 – Frequently Asked Questions

1) How do I pick the right Eaton FH heater element for my motor?
Pick by the motor's full load amps off the nameplate, then match it to the FH element whose FLA band contains that value. The A200/B100 range runs from .29-.31A (FH50) at the low end up through 23.0-25.2A (FH49), with steps like .97-1.06A (FH15), 3.00-3.28A (FH27), 6.3-6.8A (FH35), 12.0-13.1A (FH42) and 20.1-21.9A (FH48). The bands are narrow and do not overlap, so a motor drawing 8.0A takes the FH37 (7.6-8.2A), not the next size up.
2) Will an FH heater fit a NEMA Size 2 starter?
Yes. The Eaton A200/B100 FH heater elements are made for NEMA Starter Sizes 0, 1 and 2. If your starter is Size 3 or larger, this heater series is not the right part.
3) My motor nameplate reads 18.5 FLA. Which Eaton heater do I order?
The FH46 covers 17.3-18.9A, so an 18.5A motor falls in that band. Note that the neighbouring FH47 is 16.4-18.0A and FH45 is 15.8-17.2A, so the part numbers do not run in strict amperage order. Read the band, not the sequence.
4) Do Eaton FH heaters work with both Type A and Type B overload relays?
They do. The A200/B100 heater series is listed for use with Type A and Type B overload relays, so the same element covers both Eaton starter platforms rather than forcing a separate part number per relay type.
5) Can I use an FH heater element as a drop-in replacement in an existing motor control center?
That is the usual application. These are replacement heater elements for NEMA Size 0, 1 and 2 starters already installed in motor control centers and starter panels, used for overload relay maintenance and retrofits. Confirm the starter takes a Type A or Type B overload relay and order by the motor's FLA band, not by the number stamped on the old heater if the motor has since been changed.
6) Is one heater element enough, or do I need one per phase?
Heater elements are sized and sold individually by FLA band, and a three phase NEMA starter carries a heater in each pole. Order matching elements for every phase your overload relay is set up for, all from the same FLA band, so the trip point is consistent across poles.
7) What kind of trip response do these Eaton overload heaters give?
Thermal and fast trip. The element heats in proportion to motor current and trips the overload relay on a sustained overload, with a fast trip response for harder faults. It is a NEMA design part, so it follows NEMA motor control practice rather than an IEC class rating.
8) What is the smallest motor these Eaton heaters will protect?
The bottom of the range is the FH50 at .29-.31A, which suits very small fractional horsepower loads. The next steps up are the FH15 at .97-1.06A and FH16 at 1.07-1.16A, so there is a gap between roughly .31A and .97A in this heater group.
