Eaton Cutler-Hammer H2016B-3 Heater
The Eaton Cutler-Hammer H2016B-3 is a precision-engineered NEMA thermal overload heater pack designed for high-demand HVACR and industrial motor control applications. This set of three Class 20 heater elements is specifically calibrated for a Full Load Amperage (FLA) range of 39.6 to 57.4 Amps, providing essential motor overcurrent protection during prolonged starting torque scenarios. Engineered for integration with Freedom Series starters and Citation Series motor controllers, these bimetallic overload relays utilize indirect heating to accurately monitor thermal fluctuations in the motor windings. The Standard Trip Class 20 rating ensures the motor can sustain higher inrush currents during startup without nuisance tripping, making it ideal for heavy-duty compressor motors and high-inertia fan loads. Built to rigorous Eaton electrical specifications, these heaters ensure operational reliability by preventing insulation degradation caused by excessive heat, thereby extending the service life of critical HVAC motor control systems.
Key Benefits for Contractors- Precise FLA Calibration: Covers the 39.6 through 57.4 Amp range, allowing for field-adjustable protection based on nameplate data.
- Class 20 Trip Curve: Specifically accommodates motors with longer acceleration times, preventing premature tripping of the overload relay.
- Direct Compatibility: Designed for seamless installation into Cutler-Hammer NEMA Starters, ensuring proper alignment and thermal contact.
- Ambient Compensation: The thermal heater design maintains consistent performance across varying mechanical room temperatures.
What NEMA starter sizes is the H2016B-3 compatible with?
This heater pack is typically utilized in NEMA Size 2 starters within the Freedom and Citation product lines, provided the motor FLA falls within the 39.6-57.4 range.
Can these heaters be used for single-phase motor protection?
Yes, however, they must be installed across all phases of the overload relay block to ensure the sensing mechanism functions according to the thermal trip curve.
How do Class 20 heaters differ from Class 10 heaters?
Class 20 thermal units allow for a 20-second trip time at 600% of the FLA, providing a longer window than Class 10 units for motors that require additional time to reach full operating speed.
