An MCC cabinet with fixed drawers is a low-voltage switchboard containing a series of non-removable “drawers” or compartments. Each drawer is dedicated to the control and protection of a single utility, typically an electric motor.
Main features:
	- Internal separation: drawers are physically separated from each other and from the main busbar system. This separation, in accordance with IEC EN 61439-2, ensures a high level of safety by limiting the propagation of any faults (such as an electric arc) to other parts of the switchboard.
 
	- Dedicated componentsspace inside each drawer is designed to hold all the components required for starting, controlling and protecting the motor.
 
	- Busbar system:  a system of copper or aluminium bars, positioned vertically or horizontally within the cabinet, distributes the energy to the individual drawers.
 
	- Cable compartment:  a dedicated area, often to the side or rear, facilitates the entry and connection of power and control cables from the field.

Simple wiring:installation and wiring can be simpler and more straightforward.
Less mechanical maintenance required: the absence of moving parts reduces the need for maintenance on connection mechanisms.
