Thermal overload protection

The Eaton H2014B-3 thermal unit provides overload protection for motor starters in the Freedom Series. Each unit covers a full-load current range of 23.5 to 38.5 amperes. It is compatible with NEMA sizes 0, 00, 1, 2, 5, 6, 7 and 8. The pack contains three units for multi-starter installations.

Trip Class 20 behaviour

Trip Class 20 means the unit allows a longer acceleration period before tripping under sustained overload. This characteristic suits applications with high-inertia loads or frequent starts where brief current peaks are normal. The thermal mechanism responds to heating over time rather than instantaneous peaks.

Current range 23.5 to 38.5 A

Select this pack only when the motor nameplate current falls between 23.5 and 38.5 amperes. Motors outside this range require a different thermal unit rating. The NEMA size compatibility does not override the current-range requirement.

Questions about this item

Does the H2014B-3 thermal unit generate noticeable heat or noise during continuous operation?

The thermal unit is a passive overload protection device with no moving parts, so it produces no audible noise and negligible heat beyond normal current flow.

What existing hardware is required for the H2014B-3 to function in a motor starter?

It must be installed in a compatible Freedom Series starter — NEMA Size 0, 00, 1, 2, 5, 6, 7 or 8 with Frame Size G, H, J or K — to provide Trip Class 20 overload protection.

Will the H2014B-3 work with older Cutler-Hammer starters that use the same NEMA sizes?

Yes, it is compatible with Series Freedom starters in the listed NEMA sizes and frame sizes, replacing thermal units rated for 23.5 to 38.5 A full-load current.
