Eaton NEMA Overload Relay Heater Coil, Type A/B, Thermal-Fast Trip

The Eaton NEMA Overload Relay Heater Coil is a Type A and B thermal-and-fast-trip heater element engineered for use with NEMA Starter Sizes 0, 1, and 2. Built to Eaton's NEMA design standard, this heater coil protects motor circuits by tripping the overload relay in response to sustained overcurrent conditions, helping safeguard connected motors from thermal damage. Its compact footprint — roughly 1.3 in wide, .8 in high, and 2.1 in deep — allows it to fit directly into Eaton A200/B100 series overload relay assemblies without modification.

Key Features

  • Compact Dimensions: Product Width 1.3 in, Product Height .8 in, and Product Length/Depth 2.1 in for a precise fit inside Eaton A200/B100 overload assemblies.
  • Overload Relay Type: Designed for Type A and B overload relays, providing thermal and fast trip response to overcurrent conditions.
  • Starter Compatibility: Used with Starter Sizes 0, 1, and 2, making it a direct-fit replacement or upgrade heater element for these NEMA starter frames.
  • NEMA Design: Manufactured to NEMA design standards for consistent performance in industrial and commercial motor control applications.
  • FLA-Based Selection: Heater coils are selected based on the full load current (FLA) shown on the motor nameplate to ensure accurate overload protection.
  • Rated for Standard Motor Conditions: Heater coils are rated to protect against a 40°C temperature rise with a 1.15 service factor.
  • Phase-Specific Quantities: Single-phase motor circuits require 2 heater coils, while three-phase motor circuits require 3 heater coils for complete overload protection.
  • Thermal and Fast Trip Protection: Combines standard thermal trip response with fast trip capability for improved motor circuit protection.

Eaton FH06 – Frequently Asked Questions

1) How do I pick the right Eaton FH heater coil for my motor?
Selection is by the full load current (FLA) stamped on the motor nameplate, not by horsepower. The Eaton Type A/B heater coils cover FLA bands: FH03 for .29-.31A, FH04 for .32-.35A, and FH06 for .40-.43A. Match the nameplate FLA to the band it falls in. The ratings assume a motor with a 40 degree C temperature rise and a 1.15 service factor.
2) How many heater coils do I need to order for a three-phase motor?
Three. A three-phase motor circuit takes three Eaton heater coils, one per pole. A single-phase circuit takes two. They are sold as individual elements, so order the quantity for the circuit, all of the same FLA rating.
3) My motor nameplate reads 0.38A FLA. Which Eaton heater coil covers that?
None of the three FH coils in the .29 to .43A span covers 0.38A: FH03 stops at .31A, FH04 runs .32-.35A, and FH06 picks up at .40A. Eaton's FLA tables are continuous across the full FH range, so you need the intermediate FH element for that band rather than rounding up to FH06, which would let the motor draw above its nameplate current before tripping.
4) Can I use these Eaton heater coils as a direct replacement in an existing starter?
Yes, for maintenance and retrofit work on Eaton A200/B100 overload relay assemblies in Starter Sizes 0, 1, and 2 these are a direct-fit heater element, no modification to the assembly. Replace all coils in the circuit with the same FLA rating rather than mixing bands.
5) What does thermal and fast trip mean on an Eaton overload heater coil?
The Type A and B heater element gives standard thermal trip response to sustained overcurrent plus a fast trip element that reacts more quickly to severe overloads such as a stalled or locked rotor. You get both behaviours from the one coil, so there is no separate fast-trip part to order.
6) Is the Eaton FH heater coil a Type A or Type B element?
Both. The FH series heater coil is rated for Type A and Type B overload relays, so the same element covers either relay type within Eaton's NEMA A200/B100 line. Check the relay block in your starter is one of those two before ordering.
7) How much room does an Eaton FH heater coil take up in the panel?
Each element measures 1.3 in wide, .8 in high, and 2.1 in deep. That is the footprint per coil, so budget three side by side for a three-phase starter when you are laying out a tight control panel or MCC bucket.
