Eaton H1041 Overload Relay Heater Element

Product Description

The EATON H1041 is a thermal overload heater element designed for use with Type ST, BNC, and LT overload relays. Heater elements like this one protect motors from overload conditions by generating heat in proportion to motor current draw, tripping the relay when current exceeds safe limits for a sustained period. This is a small-form-factor element weighing 0.02 pounds and measuring 1.9 x 1.3 x 0.8 inches, making it a direct-fit replacement in compatible EATON overload relay assemblies. Installation is typically performed by licensed electricians during motor starter maintenance or control panel service.

Thermal overload heater elements are used in motor starter and control panel assemblies across residential, commercial, and light industrial applications. The H1041 is matched to a specific current range and is selected based on the full-load amp rating of the motor being protected. It fits into the heater element pocket of the relay and works in conjunction with the bimetallic trip mechanism. Proper element selection is critical to ensure accurate overload protection and prevent nuisance tripping or motor damage.

Key Features

• Compatible with Type ST, BNC, and LT EATON overload relays
• Thermal heater element design for proportional current-based overload protection
• Compact form factor: 1.9 x 1.3 x 0.8 inches
• Lightweight at 0.02 pounds for easy handling during panel work
• Direct-fit OEM-style replacement element

Compatibility

Designed for use with EATON Type ST, BNC, and LT overload relays. Select the correct heater element based on the full-load amp (FLA) rating of the motor and the relay model in service.

Installation Notes

Installation should be performed by a qualified electrician. De-energize and lock out the motor starter panel before removing or installing heater elements, following NFPA 70E lockout/tagout procedures. Verify the heater element current range matches the motor full-load amp rating before installation. Do not substitute heater elements across incompatible relay types, as improper elements will not provide accurate overload protection.
