Eaton H1116 T1114 Thermal Overload Heater Elements, Class 20

Eaton H1116 T1114 Thermal Overload Heater Elements

The Eaton H1116 and T1114 thermal overload heater elements provide dependable motor protection for Cutler-Hammer overload relays and motor starters. Designed for precise trip performance, these heaters use a eutectic alloy to sense excess current and activate the connected overload relay, helping to prevent motor overheating and equipment damage.

Why It Helps
These heater elements improve motor reliability by ensuring that overload conditions are detected quickly and accurately. Their Class 20 trip characteristics support balanced protection for standard industrial motors, while the Citation Series and Freedom NEMA compatibility allows seamless integration into existing Eaton control systems.

Key Highlights

• Accurate overload response: Uses a eutectic alloy to activate the overload relay when motor current exceeds safe levels, providing consistent trip performance.

• Model-specific protection: Each heater matches a specific FLA range—0.896–1.14 A for H1116 and 0.7–0.86 A for T1114—to ensure proper protection without nuisance tripping.

• Broad system compatibility: Works with Citation Series, Type ST, and BNC overload relays, as well as Freedom NEMA motor starters, supporting both enclosed and open NEMA sizes up to 1-1/2.

• Essential motor safety: Helps prevent overheating and motor damage by interrupting the control circuit during overload events.

System Compatibility
Integrates with Eaton and Cutler-Hammer overload relays and motor starters within the Citation Series, Type ST, BNC, and Freedom NEMA families.

Applications
Ideal for industrial motor protection in systems requiring Class 20 trip performance. Suitable for motor control centers, machine operation panels, and standard motor starter assemblies where reliable overload protection enhances equipment longevity and system safety.
