Eaton Cutler-Hammer H2005B-3 Heater
For veterans in the field, selecting the right overcurrent protection is about precision and equipment longevity. The Eaton Cutler-Hammer H2005B-3 Heater Pack is a critical component for Eaton Freedom Series and Definite Purpose starters, specifically engineered to provide Class 20 overload protection. This set of three heaters covers a full load amp (FLA) rating of 1.20 to 1.96 Amps, making it an essential pick for small motor loads where a standard trip time of 20 seconds or less at 600% of the rating is required to prevent thermal damage to windings.
Designed for seamless integration with C306DN3B overload relays and NEMA sizes 00 through 2, the H2005B-3 utilizes an adjustable bimetallic ambient compensated design. This allows for a ±24% adjustment range to accurately match your motor's specific nameplate FLA and service factor. These NEMA heater coils are built with high-strength, temperature-resistant materials to withstand the rigors of industrial environments while ensuring reliable motor control and thermal overload protection. When you are looking for a drop-in replacement that maintains UL Listed and CSA Certified compliance, this Eaton H-Type heater set ensures your 3-pole applications remain protected against persistent overcurrent conditions.
Key Benefits- Adjustable Range: Provides a 1.20 to 1.96 FLA range with four distinct dial positions (A: 1.20A, B: 1.45A, C: 1.71A, D: 1.96A) for precise motor matching.
- Universal Compatibility: Works with both NEMA and IEC Freedom Series 32A and 75A overload relays, ensuring versatile fitment across various motor starters.
- Enhanced Protection: The Class 20 trip rating is ideal for standard motor applications, offering the necessary delay to avoid nuisance tripping during startup while providing robust thermal protection.
- Field-Proven Reliability: The bimetallic ambient compensated design ensures the trip point remains consistent regardless of fluctuating temperatures within the enclosure or mechanical room.
What is the difference between Class 10 and Class 20 heaters like the H2005B-3?
A Class 20 heater pack is designed to trip within 20 seconds at a 600% overload, making it suitable for general-purpose motors. Class 10 is faster (10 seconds) and typically used for hermetic or submersible motors with more sensitive thermal limits.
Are these compatible with both Series A and Series B Freedom starters?
The H2005B-3 is designed for Freedom NEMA Series B and later. It is used with overload relays where the load lugs are built into the relay base, simplifying the installation of the heater pack itself.
Do I need three heaters for a single-phase motor?
While used in a 3-pole block, code and manufacturer specifications typically require the use of all three heaters in the assembly to ensure the internal tripping mechanism of the thermal overload relay functions as designed, even in single-phase applications.
