Motor Control Centers
Motor controllers are electronic devices that regulate the start, stop, and protection of electric motors. An essential component in many industrial facilities' electrical infrastructure, Motor control centers (MCC's) are the electrical enclosures that house the motor controllers to enable the functionality of equipment and machinery from a single, central location.
What's the difference between an MCC drawer and MCC bucket?
Motor control center in-bucket and in-drawer options are modular units designed to simplify the installation and replacement of motor controllers. The MCC 'bucket' is typically square or cube-shaped, whilst the drawer is exactly what you might imagine - drawer-shaped. The primary reason for these two component design options is how they are mounted, and the standard they comply with: MCC buckets are ANSI compliant for North America and some selected regions, and MCC drawers are IEC compliant, typically covering the rest of the world.
Both MCC buckets and drawers are typically made of metal and are intended to keep the motor control center safe from external elements, and provide a simpler and more versatile way of providing motor control for electrical power distribution.
MCC's typically comprise the following parts:
-
A power distribution system to provide electricity to a motor control center
-
Several motor controllers
-
A control panel from which operators can start, stop, and monitor motors
-
A safety mechanism that safeguards motors against overloads and other risks
