Eaton H2021-3 – Frequently Asked Questions

1) Does the Eaton Freedom heater pack come as one heater or three?
Three. Freedom heater packs ship 3 to a carton, and the catalog number covers the set of 3. That is what you want for a three phase motor starter, where each phase needs its own heater element, so one catalog number covers a complete three pole overload relay.
2) Which overload relays do these Freedom heater packs work with?
They pair with the matching Freedom overload relay rated 105 or 144A. The heater pack is only half of the protection scheme, the element sets the current point and the relay does the tripping, so both have to be the matched Freedom pair for the calibration to hold.
3) How do I pick the right heater pack for my motor full load amps?
Selection is by motor FLA, then fine tuned on the relay dial. Each Freedom heater pack covers a band of full load current ratings selectable at dial positions A, B, C and D, so you choose the pack whose range brackets the nameplate FLA and then set the dial to the exact position for that current. Two packs are offered, H2020-3 and H2021-3, the latter also covering the H2024-3 and H2026-3 designations.
4) What is the difference between the H2020-3 and H2021-3 Freedom heater packs?
Only the current band. Both are Class 20 Standard Trip Freedom packs for starter sizes 3-4 and IEC Sizes L-N (Series A), shipped 3 to a carton. H2020-3 covers one set of full load current ratings across dial positions A through D, and H2021-3 covers the next band up, also carried under the H2024-3 and H2026-3 designations. Match the pack to the motor nameplate FLA.
5) What does Class 20 mean on an Eaton Freedom Standard Trip heater pack, and when should I use Class 10 instead?
Class 20 is the trip class of the overload: the relay will trip within 20 seconds at locked rotor current. It suits motors with longer starting times or higher inertia loads like fans, pumps with high inertia, and loaded conveyors. If the motor accelerates quickly and you want faster protection, a Class 10 element is the one to specify instead. These Freedom packs are Standard Trip, Class 20.
6) Will an Eaton Freedom heater pack fit an IEC starter or only NEMA?
Both. The heater pack is built to NEMA and IEC design standards, and the application covers Freedom NEMA starter sizes 3-4 as well as IEC Sizes L-N in Series A. That matters on mixed control panels where some buckets are NEMA and others IEC.
7) How much room does an Eaton Freedom heater pack take in the starter enclosure?
The heater pack measures 2.5 in wide, 3.5 in long/deep and 2 in high. That is the footprint to check against the space inside an existing starter bucket before you order, particularly on retrofits into tight MCC sections.
