Eaton FH29 Type a B Overload Relay Heater Element

Product Description

The EATON FH29 is a thermal overload relay heater element designed for use with EATON Type A and Type B overload relays. Heater elements like the FH29 protect motor windings by responding to excess current draw, generating heat proportional to load current and tripping the relay before damage occurs. The FH29 is selected based on the full-load amperage of the motor being protected and the specific overload relay assembly in use. Licensed electricians and industrial maintenance technicians typically install and size these elements as part of motor starter assemblies in commercial and industrial electrical panels.

The FH29 heater element is suited for use in motor control centers, combination starters, and across-the-line starter configurations where EATON Type A or Type B overload relays are specified. It is commonly installed in commercial HVAC compressor circuits, pump motor controls, conveyor motor starters, and other three-phase or single-phase motor applications requiring thermal overload protection. Proper element selection based on motor nameplate full-load amps is critical for reliable protection.

Key Features

• Compatible with EATON Type A and Type B overload relay assemblies
• Thermal heater element design provides current-proportional trip response
• Compact form factor fits standard EATON overload relay housings
• Lightweight construction at 0.03 pounds for easy handling during installation
• UPC verified unit for accurate procurement and inventory tracking

Compatibility

Designed for use with EATON Type A and Type B overload relays. Specific relay model compatibility and amperage range should be confirmed against the EATON heater element selection tables prior to installation.

Installation Notes

Heater element installation and replacement should be performed by a licensed electrician in accordance with NEC requirements. De-energize and lock out the motor starter and confirm absence of voltage before removing or installing heater elements. Select the correct element number based on motor full-load amperage and the ambient temperature rating of the overload relay enclosure. Do not substitute heater elements across incompatible relay types, as incorrect sizing will result in inadequate motor protection.
