Eaton H1049 Overload Relay Heater Element

Product Description

The EATON H1049 is a thermal overload heater element designed for use with Type ST, BNC, and LT overload relays. Heater elements like the H1049 work by sensing the heat generated by motor current and tripping the overload relay when sustained overcurrent conditions occur, protecting motors from thermal damage. This component is a direct-replacement part sized to a specific current range, allowing licensed electricians and industrial maintenance techs to restore proper motor protection without replacing the full relay assembly.

The H1049 heater element is suited for light-duty and standard industrial motor starter applications where Type ST, BNC, or LT overload relay assemblies are installed. Common installation scenarios include three-phase motor starters in commercial HVAC equipment, pump panels, conveyor systems, and general-purpose motor control centers. Its compact form factor fits within standard overload relay housings without modification.

Key Features

• Thermal heater element sized for a specific current range within EATON Type ST, BNC, and LT overload relays
• Replaces worn or blown heater elements to restore motor overcurrent protection
• Compact dimensions allow drop-in fit within existing relay housings
• Lightweight construction at 0.020 pounds for easy handling during installation

Compatibility

Designed for use with EATON Type ST, BNC, and LT overload relay assemblies as a replacement heater element.

Installation Notes

Installation must be performed by a qualified electrician. De-energize and lock out the motor control panel following NFPA 70E lockout/tagout procedures before removing or installing any overload relay components. Confirm the heater element current rating matches the full-load amperage of the motor being protected before installation. Refer to the overload relay manufacturer documentation to verify correct heater selection for the application.
