Thermal Unit for Industrial Overload Protection

The Eaton H2007B-3 thermal unit provides overload protection for motor starters rated between 2.15 and 3.49 amperes. It uses a Class 20 thermal trip mechanism to disconnect power during sustained overcurrent conditions. The transparent housing allows visual inspection of the internal element. This pack contains three identical units for multi-starter installations or spares.

Fits Freedom Series Starters Across Multiple Frame

These units install directly into compatible Cutler-Hammer Freedom series starters covering NEMA sizes 0, 00, 1, 2, 5, 6, 7, and 8. They match frame sizes G through Z as listed, ensuring correct alignment with the starter's heater pocket. Selecting the proper ampere range frees the starter to protect the connected motor without nuisance tripping or delayed response. No additional hardware is required for installation.

Pack of Three Simplifies Maintenance Stocking

Supplying three units in one package lets maintenance teams replace all three phases simultaneously or keep spares on hand for future trips. Having matched units from the same lot ensures consistent trip characteristics across all phases. The pack quantity reduces reorder frequency for facilities running multiple NEMA starters. Each unit is ready to install without calibration or configuration.

Questions about this item

What full-load current range does the H2007B-3 thermal unit cover?

The Eaton H2007B-3 thermal unit covers a full-load current range of 2.15 to 3.49 A, providing overload protection for motors within that rating.

How much heat does the thermal unit generate during continuous operation?

The thermal unit operates as a Trip Class 20 overload relay, meaning it trips within 20 seconds at six times the rated current, limiting sustained heat buildup in the protected circuit.

Which starter or contactor series must I already have for these thermal units to fit?

These thermal units are compatible with Eaton Series Freedom starters and contactors in Frame Sizes G, H, J, K, P, R, S, T, V, W, X, and Z for NEMA Sizes 0, 00, 1, 2, 5, 6, 7, and 8.
