Eaton FH52 Type a and B Overload Relay Heater

Product Description

The EATON FH52 is a heater element designed for use with Type A and Type B overload relays in motor control applications. Heater elements like the FH52 provide thermal overload protection by sensing motor current draw and tripping the relay when sustained overcurrent conditions are detected. This protects motors and connected equipment from damage caused by overload, phase loss, or locked-rotor conditions. The FH52 measures 0.21 inches by 1.3 inches by 0.8 inches and weighs 0.03 pounds, making it a compact, drop-in component. It is installed by licensed electricians and industrial maintenance technicians during motor control center assembly or field service.

The FH52 heater element fits overload relay assemblies used in motor starters across residential, commercial, and light industrial applications. It is suited for installations where precise thermal overload protection is required to match the motor full-load amperage rating. Heater elements are selected based on motor nameplate current and ambient temperature, so verifying the correct element for the application before installation is essential.

Installation Notes

Heater element installation and replacement should be performed by a qualified electrician in accordance with NFPA 70 (NEC) requirements. De-energize and lock out the motor control circuit before removing or installing heater elements. Select the correct element rating based on the motor nameplate full-load amps and consult the overload relay heater selection table for the specific relay model. Do not operate the overload relay with missing or incorrectly rated heater elements.
