Mitsubishi FR-HAL-H3.7K AC Reactor for FREQROL FR Drives

The Mitsubishi FR-HAL-H3.7K (FR-HAL-H3.7K) is an AC input reactor engineered for integration with Mitsubishi Electric FREQROL FR series variable frequency drive systems. Serving as an essential power line accessory, this component is designed to improve the power factor on the power supply side of compatible inverter installations. It helps suppress harmonic currents generated by the inverter, reduces line disturbances, and coordinates with 400V class 3.7 kW motor drive setups within the FREQROL drive architecture. By attenuating high-frequency noise and stabilizing incoming electrical power, the reactor contributes to the operational reliability and longevity of connected industrial drive equipment. The FR-HAL-H3.7K is commonly implemented in industrial automation environments, manufacturing facilities, motor control centers, and processing plants where clean power delivery and harmonic mitigation are critical. This drive reactor provides a dependable solution for maintenance, retrofit, and system replacement requirements across Mitsubishi FREQROL drive installations.
