Eaton H2101B-3 – Frequently Asked Questions

1) Will an Eaton Freedom heater pack work with my 32A overload relay?
Yes. The Freedom Series heater packs are rated for use with overload relays rated 32A or 75A, so a 32A relay is a direct match. Anything outside those two relay ratings is not what these packs are built for.
2) What NEMA and IEC starter sizes do Eaton Freedom Series heater packs fit?
They cover NEMA starter sizes 00-0 (Series C) and Sizes 1-2 (Series B), plus IEC Sizes A-F (Series C) and IEC Sizes G-K (Series B). If your starter is outside that range, or a different series letter than the one listed for your size, this is not the heater pack for it.
3) How many heaters come in an Eaton Freedom H2101B-3 heater pack?
Three. Freedom Series heater packs ship 3 to a carton, and the catalog number and quantity are for the 3-pack. That is one pack per phase on a three-phase starter, so a single order covers one overload relay.
4) Is a Class 10 fast trip heater right for my motor, or do I need a slower trip class?
Class 10 means the overload trips within 10 seconds at locked-rotor current, which is the fast end of the scale. The Eaton Freedom heater packs are Fast Trip, Class 10 only. That suits motors that come up to speed quickly and loads you want off line fast. High-inertia loads with long accelerating times, big fans, centrifuges, some compressors, will nuisance trip on Class 10 and want a Class 20 or 30 arrangement instead.
5) Do I have to order a different heater for every motor full-load amp rating?
No, and that is the point of the pack. Each Freedom heater pack carries multiple dial-position current settings, at dial positions A, B, and C, so one part covers a band of motor FLA rather than a single value. You set the dial to the position matching the connected motor load. For a maintenance shop that means far fewer part numbers on the shelf.
6) What is the difference between the Eaton H2101B-3 and H2104B-3 heater packs?
Motor full-load amp coverage, nothing else. H2101B-3 covers the H2101B3/H2109B3/H2110B3 FLA range and H2104B-3 covers the H2104B3/H2114B3/H2106B3 FLA range. Both are Fast Trip Class 10 and both suit 32A or 75A overload relays. Pick by the nameplate FLA of the motor you are protecting.
7) Can I use the same Eaton heater pack on an IEC starter and a NEMA starter?
Yes. Freedom Series heater packs are built to both NEMA and IEC design standards, so a panel shop running mixed North American and international starter platforms can stock one part family instead of two. Match the size and series letter of the starter, not the standard.
8) Does an overload heater pack protect against short circuits too?
No. A heater pack is the thermal element of an overload relay, sized to the motor running current, and it protects against sustained overload and single-phasing. Short-circuit and ground-fault protection is a separate device ahead of the starter, a breaker or fuses. You need both in the panel.
