Eaton H2111B-3 – Frequently Asked Questions

1) How do I pick the right Eaton Freedom heater pack for my motor?
Selection is by motor full load amps. The Freedom Definite Purpose heater packs come in five FLA ratings: 1.28A (H2105B-3), 2.3A (H2107B-3), 3.38A (H2108B-3), 9.6A (H2111B-3) and 18.7A (H2113B-3). Read the FLA off the motor nameplate and order the pack that matches it, then set the relay dial position for the exact calibration point you need.
2) Which Eaton overload relays do these heater packs fit?
They are made for Eaton Freedom and Definite Purpose overload relays rated 32A or 75A. If the relay in your starter is one of those two frame ratings, the heater pack drops in; a relay of any other rating takes a different pack.
3) Is this a Class 10 or Class 20 heater pack?
Fast Trip, Class 10. That means the overload is sized to trip within 10 seconds at locked rotor current, which is what you want on submersibles, hermetic compressors and other motors with low thermal tolerance. If your motor needs a longer accelerating time, a Class 10 pack will nuisance trip and you should be looking at a Class 20 element instead.
4) Does the heater pack set the trip point by itself, or do I still have to adjust something?
Both. The pack establishes the current band, and the relay's dial positions A, B and C give you three calibration points inside that band. After installing the pack, set the dial to the position matching the connected motor's full load current rather than leaving it where the last element had it.
5) Will an Eaton Freedom heater pack work in an IEC-style starter or only NEMA gear?
The Freedom Definite Purpose heater packs are built to both NEMA and IEC design standards, so they are used across NEMA starters and IEC-style motor control assemblies, as long as the host overload relay is a Freedom or Definite Purpose unit at 32A or 75A.
6) Can I use these heater packs to recalibrate an existing starter after a motor change?
That is one of their main uses. When a motor is swapped for one with a different nameplate FLA, the relay body stays and only the heater pack changes, so you pull the old element and fit the pack matching the new motor's amps. The same applies to panelboard and control panel retrofits and routine overload relay maintenance.
7) I need overload protection for a small 2 amp motor on a definite purpose contactor. Is there a pack that low?
Yes. The range starts well below that: H2105B-3 covers 1.28A and H2107B-3 covers 2.3A, with H2108B-3 at 3.38A if the nameplate reads higher. All three are Fast Trip Class 10 elements for 32A or 75A Freedom or Definite Purpose relays.
8) What is the highest motor FLA covered by the Eaton H2100 series heater packs?
The top rating here is 18.7A, part number H2113B-3. Above that you are into a different heater element, but note the pack itself mounts in relays rated 32A or 75A, so the relay frame has headroom beyond the element rating.
