Eaton A200 Overload Heater Coil for Size 3 & 4 Starters, 3-Phase

The Eaton A200 Overload Heater Coil is engineered for use with A200 Starter Sizes 3 and 4 on 3-phase-only applications, providing precise thermal overload protection for motor circuits. This NEMA-design heater is available in a Non-Compensated, Ambient A rating with a full load current range of 23.3-25.6A, and is compatible with Type A and B overload relays featuring both thermal and fast-trip response. Select the correct heater coil based on the full load current (FLA) shown on the motor nameplate to ensure proper protection.

Key Features

  • Amperage Range: Non-Compensated, Ambient A rating of 23.3-25.6A for accurate motor overload sizing.
  • Starter Compatibility: Designed for use with Eaton A200 Starter Sizes 3 and 4, 3-Phase only.
  • Overload Relay Type: Compatible with Type A and Type B overload relays.
  • Trip Type: Thermal and fast trip protection helps guard motors against sustained overcurrent and rapid fault conditions.
  • Design Standard: NEMA design construction for reliable performance in industrial motor control applications.
  • Sizing Guidance: Heater coils are rated to protect at a 40 degree C rise with a 1.15 service factor; three-phase applications require three heaters.

Technical Specifications

  • Warranty: Eaton Selling Policy 25-000, one (1) year from the date of installation of the Product or eighteen (18) months from the date of shipment of the Product, whichever occurs first.

Eaton FH75 – Frequently Asked Questions

1) How do I pick the right Eaton A200 heater coil for my motor?
Size the heater to the full load amps stamped on the motor nameplate, not to the starter size. The Eaton A200 heater coils cover motor FLA bands from 25.3-27.8A (FH75) through 67-73A (FH85), with steps at 27.9-30.6A (FH76), 30.7-33.5A (FH77), 33.6-37.5A (FH78), 37.6-41.5A (FH79), 46.4-50A (FH81) and 62-66A (FH84). Find the band your nameplate FLA falls inside and order that part number.
2) How many heater coils do I need for a three-phase motor starter?
Three. The A200 heater coils are for 3-phase applications only, and a three-phase circuit takes one heater per phase, so order three of the same part number for a single starter.
3) Will these heaters fit an Eaton A200 Size 1 or 2 starter?
No. These FH-series heater coils are built for A200 starter Sizes 3 and 4 only. A Size 1 or Size 2 starter uses a different heater group, so a Size 3/4 heater will not give correct protection even if the amp band looks right.
4) Are these heaters compatible with Type A and Type B overload relays?
Yes, the A200 heater coils work with both Type A and Type B overload relays, and they provide thermal plus fast-trip response in either.
5) What service factor and temperature rise are Eaton A200 heater coils rated to protect at?
The heater coil amp bands are based on protection at a 40 degree C rise with a 1.15 service factor motor. If your motor has a 1.0 service factor or a different rise, the trip point relative to nameplate FLA changes and the heater selection needs to be adjusted accordingly.
6) Is this a compensated or non-compensated heater, and does ambient temperature matter?
These are non-compensated, Ambient A rated heaters. Non-compensated means the trip point shifts with the temperature around the relay, so if the starter enclosure runs much hotter or colder than the motor's ambient, expect the relay to trip earlier or later than the nameplate band suggests.
7) My existing Eaton A200 starter overload keeps tripping. Can I just replace the heater coils?
Yes, heater coils are the replaceable sizing element in an A200 overload relay and are commonly swapped during starter maintenance and retrofits. Before changing size, confirm the motor nameplate FLA against the band on the installed heater. If the heater matches the motor, nuisance tripping usually points at the load, wiring, or the relay itself rather than the coil.
8) Are Eaton A200 heater coils NEMA or IEC design?
NEMA design. The A200 line is NEMA-rated motor control, so these heaters drop into NEMA-style starters and motor control centers, not IEC contactor overload blocks.
9) What is the largest motor FLA these A200 heater coils cover?
The top listed band in this FH group reaches 67-73A with part number FH85. For motors drawing more than that, you need a larger heater from the A200 range and a starter size that supports it.
