Eaton FH85 Type a and B Overload Relay Heater Element

Product Description

The EATON FH85 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 FH85 sense motor current and translate excess heat into mechanical trip action, protecting motors from sustained overload conditions and burnout. At 0.05 pounds and compact dimensions of 2.1 inches by 1.3 inches by 0.8 inches, the FH85 is a small but critical component in any motor starter assembly. Licensed electricians and industrial maintenance technicians are the typical installers of this part.

The FH85 is suited for residential, commercial, and light industrial motor control applications wherever EATON Type A or Type B overload relay assemblies are installed. Common installation scenarios include motor starters in HVAC equipment, pump panels, compressor circuits, and other motor-driven loads where overload protection is required by code. The heater element must be matched to the full-load amperage of the motor being protected, so selecting the correct heater table rating is essential before installation.

Installation Notes

Installation of overload relay heater elements should be performed by a licensed electrician in accordance with NEC requirements and local codes. Always de-energize and lock out the motor control panel before removing or installing heater elements. Select the heater element based on the motor nameplate full-load amperage and the relay manufacturer's heater selection table. Do not energize the circuit until the motor starter enclosure is fully reassembled and secured.
