Circuit breaker power factor
WebPower factor is defined as the percentage ratio between the true power, measured in kilowatts (kW), and apparent power, measured in kilovolt amperes (kVA). The apparent power is the total requirement that a facility places upon the utility to deliver voltage and current, without regard to whether or not it does actual work. WebFeb 19, 2024 · One important reason for circuit breakers to exist is that heat generated by current in wiring could cause a fire. Power carried by a wire does not cause as much heating if the current is very low and the …
