The Cutler-Hammer FH84 Overload Relay Solid Heater, catalog number 179C319G14, is a thermal overload relay heater element designed to provide reliable motor protection in industrial applications. Key Features Thermal Fast Trip Mechanism: Ensures rapid response to overcurrent conditions, safeguarding motors from potential damage. Full Load Amperage Range: Suitable for motors with a full load current between 62 to 66 amperes. NEMA Size Compatibility: Compatible with NEMA Size 3 and 4 enclosed starters, offering versatility in various motor control setups. UL and CSA Approvals: Meets industry standards for safety and performance, ensuring compliance with regulatory requirements. Compatibility: Designed for use with Type A and B overload relays, facilitating seamless integration into existing systems. Additional Specifications Ambient Temperature Considerations: Heater coils are rated to protect 40°C rise motors and open and drip-proof motors with a service factor of 1.15, assuming the motor and controller are at the same ambient temperature. Adjustments for Ambient Temperature Variations: If the controller’s ambient temperature is 26°C lower than the motor’s, use one size smaller coil. If the controller’s ambient temperature is 26°C higher than the motor’s, use one size larger coil. Ultimate Tripping Current: Approximately 1.25 times the minimum current rating, providing an additional safety margin. Warranty: Backed by a 1-year warranty from the date of installation or an 18-month warranty from the date of shipment, whichever comes first. The FH84 heater element is an essential component for maintaining the efficiency and longevity of motor control systems, offering dependable protection against overload conditions.
