Eaton h1111 Heater Coil

Product Description

The EATON h1111 is a replacement heater coil designed for use in motor starters and overload relay assemblies. Heater coils generate a calibrated thermal response to current flow, tripping the overload relay when sustained overcurrent conditions occur. This protects motors from damage caused by overload, phase imbalance, or locked-rotor conditions. Measuring 0.8 inches high, 1.3 inches wide, and 2.1 inches deep, the h1111 is a compact element suited for panel-mounted motor control equipment. Installation is typically performed by licensed electricians or qualified motor control technicians.

This heater coil is intended for use in Freedom NEMA-style motor starters and associated overload relay assemblies. It is part of the Citation and miscellaneous accessories product family within the EATON Freedom NEMA lineup. Typical applications include commercial and industrial motor control panels where thermal overload protection is required for three-phase or single-phase motor circuits.

Installation Notes

Heater coil replacement should be performed by a licensed electrician or qualified motor control technician. De-energize and lock out the motor control panel before removing or installing heater elements, following NFPA 70E arc flash and lockout/tagout procedures. Verify the heater coil selection matches the full-load amperage of the motor being protected before reinstalling the overload relay assembly. Consult the motor starter documentation for proper seating and retention of the heater element.
