Thermal unit for motor protection

The Eaton FH24 thermal unit provides overload protection for industrial motor starters. It covers full-load current ranges of 1.96 to 2.15 A and 2.27 to 2.48 A with a Trip Class 20 response. The transparent housing allows visual inspection of the element. It fits NEMA Size 0, 1 and 2 starters.

Transparent housing and series compatibility

The clear casing lets maintenance staff confirm element condition without removal. It mounts directly into compatible Series A200 and B100 starters. The unit matches Grainger part numbers 11Z488 through 11Z497 for straightforward identification during replacement.

Replaces worn thermal elements in existing starters

This unit restores overload protection when the original element has tripped or drifted out of calibration. The upgrade is worth it when the starter frame is sound but the thermal element no longer holds its rated current band. Buyers needing electronic overload relays or communication-enabled protection will not find those features here.
