Mitsubishi FR-HEL-0.4K DC Reactor for FREQROL FR Inverters

The Mitsubishi FR-HEL-0.4K (FR-HEL-0.4K) is a drive component and power-factor-improving DC reactor engineered for Mitsubishi Electric FREQROL FR series variable frequency drives. Designed for use with 0.4 kW inverter systems, this reactor connects into the intermediate direct-current link to improve power factor and attenuate harmonic currents generated on the power supply line. By smoothing ripple currents within the drive's DC circuit, the unit reduces electrical stress on internal converter components, enhances overall operating efficiency, and protects connected industrial automation equipment from supply disturbances. Built for seamless integration into FREQROL drive installations, the FR-HEL-0.4K is deployed across factory automation environments, machinery controls, pump systems, fan drives, and conveyor applications. It helps installations meet harmonic suppression standards while extending the operational life of the frequency inverter. Its rugged design ensures stable performance during continuous industrial duty cycles.
