The JD2225 is a thermal-magnetic circuit breaker that has been manufactured and designed by Cutler-Hammer. This circuit breaker is distributed by the Eaton Corporation. It belongs to Series C of the Cutler-Hammer circuit breakers, specifically to the Frame J frame range. The Cutler-Hammer JD2225 thermal-magnetic circuit breaker has a standard interrupting capacity of 35 symmetrical Amps at a specific voltage of 480 Volts AC. It operates with a full range voltage of up to 600 Volts AC, a frequency of 50/60 Hertz, and a maximum continuous amperage of 225 Amps at a temperature of up to 40 degrees Celsius. The maximum ambient air temperature recommended for the Cutler-Hammer JD2225 thermal-magnetic circuit breaker is 40 degrees Celsius.
If a higher ambient temperature than 40 degrees Celsius is required, then a new calibration process must be performed or the breaker has to be derated. If the breaker is going to be used inside an enclosure, the slow heat dissipation will cause it to lose capacity, so further derating might be needed. The Cutler-Hammer JD2225 thermal-magnetic circuit breaker features 2 poles, and these are both able to detect short-circuits and abnormal currents. This circuit breaker works with a thermal mechanism that consists of 2 metal bars that are going to receive heat from the line current and with magnetic mechanisms that consist of electromagnets placed in series. Once the circuit breaker has detected a fault, it can be put back into operation once the fault has been cleared. The Cutler-Hammer JD2225 thermal-magnetic circuit breaker features interchangeable trip units, and it is a factory assembled circuit that has a frame, trip units, and terminals.
