Eaton Cutler-Hammer FH28 Heater
When you are outfitting NEMA Size 0, 1, or 2 starters, selecting the correct thermal protection is non-negotiable for system longevity. The Eaton Cutler-Hammer FH28 Heater is a thermal-overload element designed specifically for Type A and B overload relays within the A200 and B100 series. As a veteran tech, you know that Full Load Amps (FLA) accuracy is what prevents nuisance tripping while ensuring the motor doesn’t burn out under stress. This FH series heater element provides a reliable current rating range of 3.22 to 3.53 Amps for non-compensating relays, with slightly different ranges for ambient compensated units (typically 2.84 to 3.60A). Its thermal and fast trip characteristics ensure your magnetic motor starters react precisely to overcurrent conditions. Built for industrial-grade motor control and protection, the FH28 is standard in many HVACR and pump control panels. Ensure you match the motor nameplate FLA to the specific heater table for 40°C rise and a 1.15 service factor to guarantee proper overload relay calibrated performance.
Key Benefits- Universal Compatibility: Seamlessly integrates with Eaton Cutler-Hammer Type A and B overload relays and NEMA Size 0-2 starters.
- Precision Thermal Response: Engineered for fast trip protection, minimizing the risk of winding damage during a locked-rotor or heavy overload event.
- Robust Construction: Designed for industrial motor control environments, providing consistent calibration across its 3.22-3.68 Amp range.
- Code Compliance: Facilitates NEC Article 430-32 compliance for motor branch-circuit overcurrent protection when sized according to manufacturer charts.
Is the FH28 compatible with both ambient compensated and non-compensated relays?
Yes, the FH28 heater element is designed for use in both, though the Full Load Amps (FLA) trip range will vary based on the specific overload relay housing used. Always refer to the internal door chart of your starter for the exact amperage range.
How many heaters are required for a three-phase motor application?
For standard three-phase starters, you must install three FH28 heaters to ensure all lines are protected. Single-phase applications typically require two elements.
Can I use an FH28 in a Size 3 starter?
No, FH series heaters like the FH28 are specifically engineered for use with NEMA Size 0, 1, and 2 starters. Larger frame sizes require different heater series or electronic overloads.
