How to Specify the Right Motor Control Center For the job: When purchasing a new or replacement MCC be sure to address a few important items in your specification

摘要

Motor control centers (MCCs) were first introduced in 1937 as a way to conserve wall and/or floor space in industrial facilities. Before 1960, wall-mounted motor starters were used even if only a few motors were involved. Relays were housed in separate control cabinets. Today, even if a few motor starters are needed, they're typically installed within a standardized vertical enclosure with all the required relays, instruments, and controls. Overall, the same requirement today often dictates the use of MCCs in new installations.
