Eaton Cutler-Hammer H2021-3 Heater
The Eaton Cutler-Hammer H2021-3 Heater is a critical thermal protection component designed for NEMA Size 3 and 4 motor starters. Engineered for use within the Freedom Series and definite purpose starters, these heaters offer a Full Load Amp (FLA) rating of 45.7 to 62.1 Amps. As a Class 20 standard trip heater pack, this set of three provides the necessary time-delay characteristics to allow for motor inrush currents during startup while ensuring robust protection against sustained overloads that could damage motor windings.
For technicians performing field adjustments, the H2021-3 features a calibrated dial with four distinct positions: Pos A (45.7A), Pos B (51.2A), Pos C (56.7A), and Pos D (62.1A). These heater elements are compatible with 105A or 144A overload relays and are specifically required for Series A overload relay bases where load lugs are not integrated into the heater pack itself. Relying on bimetallic thermal overload technology, these elements ensure reliable performance in demanding industrial HVACR applications and electrical control panels.
Key Benefits:- Precise Thermal Protection: Specifically calibrated for a 45.7-62.1 Full Load Amp Rating to prevent motor burnout.
- Industry Standard Compliance: Meets Class 20 trip requirements, ideal for heavy-duty motors with longer acceleration times.
- Broad Compatibility: Engineered for Eaton Freedom Series motor control centers and NEMA Size 3-4 starters.
- Convenient Packaging: Supplied as a set of 3 to provide complete phase protection for three-phase motor systems.
- Which overload relay is compatible with the H2021-3? These heaters are designed for use with 105A or 144A Freedom Series overload relays.
- Are these suitable for IEC starters? Yes, they are compatible with IEC Sizes L through N (Series A) starters.
- How do I set the FLA? Use the A-B-C-D dial positions on your overload relay to match the motor's nameplate FLA within the 45.7A to 62.1A range.
