Eaton H1028 Overload Relay Heater Element

Product Description

The EATON H1028 is a thermal overload heater element designed for use with Type ST, BNC, and LT overload relays. These heater elements generate a calibrated amount of heat in proportion to motor current, which trips the overload relay when sustained overcurrent conditions occur. The H1028 is selected based on the full-load amperage of the motor being protected, making proper sizing critical to reliable motor protection. Licensed electricians and industrial maintenance technicians are the primary installers of this component in motor starter and contactor assemblies.

This heater element is suited for residential, commercial, and light industrial motor control applications where Type ST, BNC, or LT EATON overload relays are installed. Typical applications include motor starters protecting single-phase and three-phase motors in HVAC equipment, pumps, conveyors, and compressors. The H1028 is sold in cartons of 10 units, making it practical for contractors and MRO distributors who stock heater elements across multiple amperage ranges.

Compatibility

Designed as a replacement heater element for EATON Type ST, BNC, and LT overload relays. Verify the full-load amperage rating of the motor and the overload relay series before selecting a heater element to ensure proper trip characteristics.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC guidelines and applicable local codes. De-energize the motor starter and lock out and tag out the disconnect before servicing any overload relay or heater element. Select the heater element based on the motor nameplate full-load amperage and the manufacturer sizing chart for the specific relay type. Do not substitute heater elements across incompatible relay families, as incorrect sizing will result in inadequate motor protection.
