A motor control center (MCC) is a congress of single or multiple enclosed sectors having a ordinary power bus and mainly having motor control units. Motor control centers are in contemporary perform a factory assembly of some motor starters. A motor control center can contain changeable frequency drives, programmable controllers and metering, it may also be the electrical service access for the building. Motor control centers are typically used for low power three phase blinking current motors from 208 V to 600 V. average voltage motor control centers are complete for large motors running at 2300 V to around 15000 V, with vacuum contactors for controlling and with divide sections for power switching and control.
Since 1950, a motor control center (MCC) has been used by the automobile manufacturing industry; they used huge figures of electric motors. Now they used in lots of industrial and commercial purposes. Where extremely cutting processes are used, the motor control center may be set up in a split air-conditioned room, but regularly an MCC will be on the factory floor neighboring to the machinery controlled.
A motor control center consists of single or multiple perpendicular metal cupboard sections with power bus and condition for connect mounting of individual motor controllers. Extremely huge controllers may be locked in place but slighter controllers can be unlocked from the cupboard for testing or preservation. Every motor controller hold a contactor or a solid-state motor controller, excess relays to guard the motor, fuses or a circuit breaker to supply short-circuit guard, and a disconnecting switch to separate the motor circuit. Every motor controller in an MCC can be particular with a variety of choices such as separate control transformers, control switches, extra control terminal blocks, pilot lamps, different types of thermal overload protection relays.
Duly wired with ACB/MCCB/SFU/DOL/STAR-DELTA/ATS Starters. Various designs provided like single/double front, fixed type, with marshaling terminations.
