When selecting a Load Reactor, four core electrical parameters need to be focused on. First is the rated current, which must match the operating current of the circuit it is in. If the rated current is less than the actual current, the Load Reactor will overheat and be damaged. Usually, a current margin of 10%-20% needs to be reserved.
Second is the rated inductive reactance. The inductive reactance value directly affects the current-limiting and filtering effects, and it needs to be calculated and determined according to the circuit requirements. For example, when suppressing harmonics, the corresponding inductive reactance must be matched according to the harmonic frequency to avoid protection failure caused by inconsistent parameters.
Third is the rated voltage, which must be consistent with the circuit system voltage, including the rated operating voltage and short-time withstand voltage. This prevents the insulation layer of the Load Reactor from being broken down due to excessive voltage.
Finally, there is the temperature rise limit. Load Reactors of different materials have clear temperature rise standards, and selection must be based on the operating environment temperature. For instance, in high-temperature environments, products with higher temperature rise limits should be chosen to avoid performance degradation after long-term operation, ensuring the Load Reactor stably adapts to the circuit's operating needs.
