Allen-Bradley 160-CMB1 PLC Module

Allen-Bradley 160-CMB1 External Capacitor Module is an accessory for the Bulletin 160 Series variable-speed drives. It provides the external capacitor bank required by the drive’s power stage and is rated for 380–460 VAC, 3‑phase service. Catalog number 160-CMB1; designed for use with Allen-Bradley 160 Series drive configurations that call for an external capacitor solution on 380–460 V three‑phase systems. This module is intended for industrial motor control applications where robust startup behavior and DC-bus voltage support are needed for higher-voltage motors. Typical use cases include conveyors, pumps, fans, and other industrial loads powered from a 380–460 V three‑phase supply. The 160-CMB1 is part of the 160 family’s power accessory lineup and is selected when the specified drive configuration requires an external capacitor module to achieve proper performance in high-voltage installations.
