Eaton H1038 Overload Relay Heater Element

Product Description

The EATON H1038 is a heater element designed for use with Type ST, BNC, and LT overload relays. Heater elements are thermal sensing components installed inside overload relay assemblies to protect motors and electrical equipment from sustained overcurrent conditions. When current exceeds the rated threshold, the heater element generates enough heat to trip the relay and interrupt the circuit. Licensed electricians and industrial maintenance technicians install these elements as part of motor starter and contactor assemblies in commercial and industrial electrical systems.

The H1038 heater element is suited for motor protection applications where Type ST, BNC, or LT series EATON overload relays are specified. These relays are commonly found in motor control centers, panel-mounted starters, and combination starter units in light commercial and industrial settings. The heater element must be matched to the full-load amperage of the motor being protected, making correct element selection critical to proper overload protection.

Key Features

• Compatible with EATON Type ST, BNC, and LT overload relay assemblies
• Thermal heater element design provides passive, reliable motor overcurrent protection
• OEM-style replacement element for maintaining factory-rated trip characteristics
• Compact form factor suited for motor control center and panel-mounted starter installations

Compatibility

Designed for use with EATON Type ST, BNC, and LT series overload relays. Verify the full-load amperage of the motor and cross-reference the EATON heater element selection chart before installation to confirm proper trip rating.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NFPA 70 (NEC) and applicable local codes. De-energize and lock out the motor control panel before removing or installing heater elements. Confirm the replacement element matches the motor full-load amperage rating — installing an incorrect heater element will result in improper overload protection. Do not energize the relay assembly until all elements are properly seated and the enclosure is secured.
