Fixed MCC switchboards

The Prisma Plus functional system can be used for

low-voltage MCC switchboards in commercial (IP30)

and industrial (IP55) environments.

It has been tested taking into account device

characteristics.

This ensures a high degree of reliability in system

operation and optimum safety.

Devices can be premounted on mounting plates on a

workbench to simplify installation in the switchboard.

The fixed functional system for Motor Control Centers

is designed for installation of motor feeders up

to 37 kW.

Motor Control Centers (MCC)

AMotor Control Center is a switchboard comprising a

group of motor feeders, each used to:

control a motor

protect personnel

protect all devices and equipment against electrical

faults.

The basic functions implemented to achieve these

objectives are:

disconnection to isolate the motor feeder from the

main power supply, generally associated with an

emergency-off switch

protection against short-circuits to avoid equipment

damage

power control to allow on-load making and breaking

of the electric current

thermal protection to prevent overheating.

Isolation is a complementary function that allows work

to be carried out safely on the motor. This function is

generally implemented near the motor.
