Thermal Unit for Motor Overload Protection

The Eaton FH41 thermal unit provides overload protection for motor starters in industrial control panels. It suits maintenance engineers and electricians who need to match a specific full-load current range on NEMA Size 0 1 or 2 starters.

Trip Class 20 Defines the Response Limit

Trip Class 20 means the unit will trip within a defined time at six times the rated current, so it protects against sustained overloads but allows normal motor starting currents. The adjustable range covers 9.5 to 10.3 A and 10.9 to 11.9 A full-load settings, so it cannot protect motors outside those bands.

Transparent Housing Aids Visual Inspection

The transparent colour lets technicians confirm the trip indicator status without removing the cover. It mounts directly into compatible Series A200 and B100 overload relays, so no extra hardware is needed, but it will not fit relays outside those series.

Questions about this item

Which FH41 thermal-unit current range should I select for my motor?

Choose the 10.41–11.30 A unit when the motor full-load current falls between 9.5 and 11.9 A; the heater is calibrated for NEMA Size 0, 1 or 2 starters.

What does Trip Class 20 mean for everyday operation?

Trip Class 20 means the thermal unit allows a standard overload duration before tripping, matching the protection curve expected for general-purpose motor applications.

Which starter series does the FH41 10.41–11.30 A unit fit?

The unit is compatible with Series A200 and B100 starters, and cross-references Grainger part numbers 11Z488 through 11Z497 for direct replacement.
