Eaton Cutler-Hammer H2022-3 Heater
When you're out in the field dealing with a tripped motor or a high-inertia load, you need a precise thermal response that doesn't cause nuisance shutdowns. This Eaton Cutler-Hammer H2022-3 Heater pack is a professional-grade solution designed specifically for the Freedom Series starters. It provides a flexible Full Load Amp (FLA) rating ranging from 62.2 to 84.6 Amps, which is easily adjustable via four distinct dial positions (A: 62.2A, B: 69.7A, C: 77.1A, D: 84.6A) to match your motor's nameplate data. As a Standard Trip Class 20 heater, these units are engineered to handle applications where the motor takes up to 20 seconds to reach full speed at 600% of its rated current. This makes them the go-to choice for heavy-duty HVACR equipment like large commercial fans, centrifugal pumps, or industrial compressors that often trigger Class 10 overloads prematurely. These genuine Eaton heater coils are compatible with NEMA Size 3 and 4 starters, as well as IEC sizes L through N (Series A). This set includes three heaters to ensure balanced protection across all phases of your three-pole overload relay, maintaining UL Listed and CSA Certified safety standards for your motor control center.
Key Benefits for Technicians:- Adjustable Dial Settings: Covers a wide 62.2-84.6A range, reducing the need to stock multiple fixed-rated heater packs.
- Class 20 Protection: Optimized for high-inertia startup cycles to prevent nuisance tripping in demanding industrial environments.
- Freedom Series Compatibility: Fits perfectly into NEMA Size 3-4 and IEC L-N (Series A) overload relays without modification.
- Standardized Set: Comes as a matching set of three to provide consistent thermal monitoring across all power leads.
- Technical Reliability: Built with high-strength, temperature-resistant insulating materials for reliable bimetallic operation.
What is the difference between Class 10 and this Class 20 heater?
A Class 20 heater allows the motor to sustain high inrush current for up to 20 seconds at 600% FLA before tripping, whereas Class 10 trips within 10 seconds. Use this H2022-3 for heavy loads that require longer acceleration times.
Are these compatible with Series B starters?
These are specifically designed for Series A and prior Freedom starters. If you are replacing heaters in a Series A relay with newer Series B components, you may require a separate lug adapter kit for proper fitment.
Can I use a single pack for a 3-phase motor?
No, for proper phase imbalance and overload protection, you must install all three heaters provided in this set into the corresponding poles of the relay.
