Motor control centers are used to operate electrical controls from a central location. Control centers can be low or medium voltage, each of which is used for different applications and settings. While both types of motor control centers have similar components, such as circuit breakers and disconnecting switches, this guide explains a few of the key differences between them so you can make the right decision for your electrical needs. 

Low Voltage Control Center

As the name suggests, a low voltage control center is designed for use with low voltage motors. In terms of voltage ratings, motors that use alternating currents ranging from 230 V to less than 1000 V are suited to low-voltage controls. In general, low voltage controls have a shorter lifespan. In cases where the controls will be running on a 24/7 basis, you can expect three to five years of efficient usage. 

When producing a vehicle, a large number of motorized devices are used, and a control center ensures efficient operation of these devices. As a result, low voltage controls are often used in automotive manufacturing.

Medium Voltage Control Center

Conversely, medium control centers are equipped for use with larger motors operating on alternating currents ranging from 1000 V to 15000 V. Unlike low voltage controls, medium voltage control centers are known for their longevity. In fact, these controls can last as long as 20 years in some cases. 

Many medium voltage control systems are typically used in industrial settings, as well as for utility generation (such as water, gas, and electrical plants). They can provide power to pumping equipment, turbines, alternators, compressors, rolling mills, and many other types of equipment.
