Eaton FH74 Type a B Overload Relay Heater Element

Product Description

The EATON FH74 is a thermal overload relay heater element designed for use with EATON Type A and Type B overload relays. Heater elements like the FH74 generate a calibrated amount of heat in proportion to motor current, allowing the overload relay to trip and protect the motor from sustained overcurrent conditions. This part is selected based on the full-load amperage of the motor being protected and is installed by licensed electricians during motor starter assembly or replacement service.

The FH74 is suited for use in motor control applications across residential, commercial, and light industrial settings. It installs into compatible EATON Type A and Type B overload relay assemblies housed within combination starters, manual motor starters, or motor control centers. Proper heater element selection is critical to accurate overload protection and must match the motor full-load amperage rating per the relay manufacturer's selection table.

Key Features

• Calibrated heater element provides proportional thermal response to motor overcurrent conditions
• Compatible with EATON Type A and Type B overload relay assemblies
• Compact form factor fits standard overload relay heater pockets
• Replaces worn or incorrectly sized heater elements during motor starter service

Compatibility

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

Installation Notes

Installation should be performed by a licensed electrician. Disconnect and lock out all power to the motor control panel before removing or installing heater elements. Verify the replacement element rating matches the motor full-load amperage using the overload relay manufacturer's heater selection table. Installation must comply with NEC Article 430 requirements for motor overload protection.
