Description
The Cutler Hammer-Eaton FH20 Overload Relay Heater is an essential part that shields electric motors from additional load current which leads to excessive heat and may otherwise damage HVAC systems type motor loads. This part works with the help of a bimetallic plate which is sensitive to heat produced by the load current of the motor. Whenever the current rises beyond the permissible limit, the plate flexes and breaks a circuit and stopping power to the motor and averting harm. The is particularly designed for HVAC systems like fans and pumps to prevent them from reaching hazards thermal conditions. Some of the advantages of this overload relay heater include improved motor protection, low mechanical failure, and long equipment life.
