Eaton FH90 Thermal Overload Relay Heater Element

Product Description

The EATON FH90 is a thermal overload relay heater element designed for use with Type A and Type B overload relays in motor control applications. Heater elements like the FH90 protect electric motors from sustained overload conditions by generating heat proportional to current draw, tripping the relay when the motor is at risk. Licensed electricians and industrial maintenance technicians install these elements as part of motor starters and combination controllers in commercial and industrial electrical panels.

The FH90 is used in motor control centers, panel-mounted starters, and combination motor controllers where Type A or Type B overload relay bases are installed. It is suited for both commercial and light industrial applications where motor overload protection is required. Technicians select the correct heater element based on full-load amperage of the motor being protected, making proper element selection critical to system reliability.

Key Features

• Compatible with Type A and Type B EATON overload relay bases
• Thermal heater design responds to motor current for accurate overload protection
• Compact form factor fits standard motor starter assemblies
• Lightweight construction at 0.07 pounds for easy handling and replacement

Compatibility

Designed as an OEM-style replacement heater element for EATON Type A and Type B thermal overload relays used in motor starter and motor control center assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lockout/tagout the motor starter or motor control center before replacing any heater element. Verify the full-load amperage of the motor and cross-reference the appropriate heater element selection chart to confirm the FH90 is the correct element for the application before installing.
