Eaton Cutler-Hammer H2003B-3 Heater
The Eaton Cutler-Hammer H2003B-3 Heater is an essential component for NEMA starters, specifically engineered for the Freedom Series and Advantage motor starters. This set of three thermal overload heaters provides precise overload protection for motors with a Full Load Amp (FLA) rating ranging from 0.560 to 0.907 Amps. As a Standard Trip Class 20 heater, it ensures reliable protection by tripping within 20 seconds at 600% of its maximum current rating, effectively preventing motor winding damage during sustained overcurrent conditions. The bimetallic sensing element offers consistent performance across various ambient temperatures, making it a staple for industrial HVACR applications requiring tight current calibration and nuisance-trip prevention.
Key Benefits for Field Installation- Precise FLA Range: Optimized for low-amperage motor protection between 0.560 and 0.907 Amps.
- NEMA Compatibility: Designed specifically for seamless integration with Eaton Freedom Series contactors and starters.
- Standard Trip Reliability: Class 20 trip curve provides the necessary lag for standard motor startups while maintaining critical protection.
- Durable Construction: Built to withstand commercial environments, ensuring long-term thermal stability and mechanical integrity.
- Direct Replacement: Simplifies maintenance workflows as a drop-in Cutler-Hammer H2003B-3 replacement.
What is the difference between Class 10 and Class 20 heaters in this series?
The Class 20 rating of the H2003B-3 allows for a longer starting time compared to Class 10, making it suitable for loads with higher inertia that require more time to reach operating speed without triggering an overload trip.
How do I verify the correct heater size for my motor?
Confirm the motor nameplate FLA falls within the 0.560-0.907 range. Always reference the starter heater selection table based on your specific motor's service factor to ensure accurate protection.
Can these heaters be used in single-phase applications?
While sold as a set of 3 for three-phase systems, they can be utilized in single-phase starters by following the appropriate wiring diagrams to ensure the thermal sensing circuit is properly closed.
