# ABB CPX Series Control and Protection Switches: A Compact and Integrated Solution for Modern Low-Voltage Systems

In today’s rapidly evolving industrial landscape, the reliability, efficiency, and safety of low-voltage power distribution systems are more important than ever. Traditional motor control and protection schemes often rely on using multiple discrete devices such as contactors, thermal relays, and circuit breakers—leading to more installation space, complex wiring, higher failure rates, and greater maintenance effort. To address these challenges, ABB has introduced the **CPX Series Control and Protection Switches**, a highly integrated product line that combines switching, protection, and control functions within a compact unit. This series reflects ABB’s deep expertise in electrical engineering and offers a modern approach to motor and load protection in industrial and commercial applications.

## Integrated Functionality for Simplified System Design

One of the defining characteristics of the ABB CPX Series is its multifunctional design. It unites the roles of circuit breakers, isolators, motor starters, and thermal overload protection—functions that traditionally require separate devices—into a single component. This integrated approach minimizes equipment count, simplifies wiring and assembly, and reduces installation time and cost.

Core functions integrated into the CPX include:

* Short-circuit protection
* Thermal and magnetic overload protection
* Motor control and start/stop functionality
* Isolation and disconnection
* Manual and remote operation capabilities

By consolidating these features, the CPX Series helps engineers design more compact and reliable systems while reducing potential failure points in the distribution network.

## Robust Motor Protection and Versatile Control

The CPX Series is particularly effective in motor protection applications. It provides comprehensive thermal-magnetic protection, ensuring that motors are safeguarded against overloads, locked-rotor conditions, phase loss, and short circuits. Such protection is essential in industries where motors operate continuously or start frequently, such as:

* Pumps and compressors
* Fans and HVAC systems
* Conveyors
* Elevators and material handling

In addition to protection, the series supports a wide range of motor control features, including direct-on-line starting and forward-reverse control options. These capabilities provide engineers and plant operators with flexible configurations to adapt to load characteristics and system requirements.
