Installation and Usage

The FH84 heater element is engineered to protect motors with a 40°C rise and a service factor of 1.15. For optimal performance, ensure that the motor and controller are operating within the same ambient temperature. If the ambient temperature of the controller is lower or higher than the motor by 26°C, it is recommended to use one size smaller or larger coil, respectively. The ultimate tripping current of the heater coils is approximately 1.25 times the minimum current rating, providing an added layer of protection against overcurrent scenarios.

Incorporating the Cutler-Hammer FH84 Overload Relay Solid Heater into your motor control system enhances operational safety and reliability, ensuring prolonged equipment lifespan and reduced downtime.
