Eaton Cutler-Hammer H2012B-3 Heater
The Eaton Cutler-Hammer H2012B-3 is a precision-engineered NEMA thermal overload heater pack designed for use with Freedom Series starters and contactors. This set of three heaters provides reliable motor protection by monitoring the Full Load Amps (FLA) within a specific range of 14.0 to 22.8 Amps. Built for industrial-grade durability, these Class 20 trip elements are essential for applications where motor startup takes longer, offering a standard 20-second trip time at 600% of the FLA setting to prevent nuisance tripping while ensuring catastrophic failure protection. Selecting the correct H2012B-3 heater element is critical for maintaining the integrity of Type AN or BN starters. The bi-metallic construction ensures consistent thermal sensing and accuracy across varying ambient temperatures. When installing, verify that your motor nameplate FLA falls within the specified range to ensure the overload relay provides optimal current sensing and circuit protection for your specific motor control center configuration.
Key Benefits
- Compatible with Eaton Freedom Series starters and NEMA-rated contactors.
- Standard Trip Class 20 rating allows for extended motor starting times without premature disconnects.
- Provides a balanced 14.0-22.8 Full Load Amp range for flexible field calibration.
- Sold as a set of 3 heaters to ensure complete phase protection for three-phase motor applications.
- Robust Eaton thermal heater specifications ensure long-term reliability in demanding HVACR environments.
Common Questions
What is the difference between Class 10 and Class 20 heaters?
Class 20 heaters, like the H2012B-3, allow for a 20-second delay at 600% of the FLA, making them suitable for high-inertia loads, whereas Class 10 heaters trip in 10 seconds for standard applications.
Can these be used with third-party motor starters?
These elements are specifically designed for Eaton Cutler-Hammer Freedom Series hardware; using them in non-compatible housings can result in improper tripping or failure to protect the motor.
How do I verify the correct heater size for my motor?
Cross-reference your motor nameplate FLA with the heater selection table found inside the starter enclosure to ensure the 14.0-22.8 Amp range is the correct match.
