Reliance Electric 6MDDH-2P3202 Variable Frequency Drive

Reliance Electric 6MDDH-2P3202 is a compact variable-frequency drive (VFD) that enables precise speed control of a small motor from a 380–480 V supply. Rated 0.75 kW (1 hp), this MD65-frame AC drive ships with a heatsink attached, offering improved heat dissipation in panel-mounted installations. In catalog listings it’s also shown as CNR-6MDDH-2P3202 under the Allen-Bradley/Rockwell Automation branding, reflecting the product lineage and cross-brand compatibility within the same drive family. The 6MDDH-2P3202 designation identifies a Reliance MD65-series module intended for reliable motor control in industrial environments where space and cooling are considerations. This model supports standard VFD capabilities, including adjustable output frequency and voltage to match motor requirements while maintaining the familiar Reliance/Allen-Bradley control topology. The heatsink-equipped MD65 enclosure makes it suitable for retrofits or panel installations where airflow is limited, and the 380–480 VAC input accommodates higher-voltage service runs common in manufacturing settings. This part provides the same electrical rating and MD65 form factor as other MD65-series modules, helping maintain a consistent installation in MD65-based control panels.
