Eaton Cutler-Hammer MSH6.6A Overload Heater
The Eaton Cutler-Hammer MSH6.6A Overload Heater is a critical thermal protection component engineered for MS Series manual motor starters. Designed specifically for single-phase motor control applications, this thermal overload heater element provides a precise trip response to protect against overcurrent conditions that can lead to motor burnout. With a functional motor full load amperage (FLA) range of 5.27A to 5.83A, it ensures reliable operation in demanding HVACR and industrial environments. This Type MSH plug-in heater is built for seamless integration into existing NEMA 1, 3, 4, or 5 enclosures, allowing technicians to maintain or upgrade Eaton manual starters with minimal downtime. The robust construction utilizes high-quality thermal conductive materials to ensure accurate heat dissipation and consistent performance across varied ambient temperatures. As a standard trip class device, it offers the dependable secondary protection necessary for pumps, fans, and small compressors in commercial HVAC systems.
Key Benefits- Precision Motor Protection: Calibrated for 5.27 to 5.83 Amperes to safeguard motors from sustained overload conditions.
- Direct OEM Compatibility: Engineered as a drop-in MSH series heater for Cutler-Hammer MS manual starters.
- Versatile Application: Suitable for use in standard NEMA enclosures common in HVACR and machinery controls.
- Efficient Thermal Management: High-grade metallic construction ensures accurate sensing of motor heat signatures.
- Safety Certified: Fully UL listed and CSA approved for professional industrial installations.
Is the MSH6.6A compatible with three-phase starters?
While the MSH series is primarily found in the MS Series single-phase manual starters, typical installations require two heater elements for single-phase and three for three-phase configurations depending on the starter body type used. Always verify the specific starter model before installation.
What determines the choice between MSH6.6A and other sizes?
Heater selection is strictly based on the Motor Full Load Amperes (FLA) listed on the motor nameplate. This specific part is designed for the 5.27A - 5.83A window; using an incorrectly sized heater will result in either nuisance tripping or inadequate motor protection.
Can this heater be used with Freedom Series contactors?
No, the MSH series is proprietary to the MS Series Manual Motor Protectors. Freedom Series or A200 starters typically utilize H2 series heaters or electronic overload modules.
