# ABB ATS-CB021 Series Automatic Transfer Switch: A Reliable Solution for Critical Power Continuity

In today’s industrial and infrastructure sectors, the reliability of electrical power systems has become more critical than ever. With the rapid expansion of data centers, hospitals, transportation hubs, manufacturing facilities, and commercial buildings, the demand for uninterrupted power is continuously increasing. Any unexpected power outage may lead to production downtime, equipment damage, or even life-threatening consequences. To address these challenges, ABB has introduced the **ATS-CB021 Series Automatic Transfer Switch**, a high-performance solution designed to achieve seamless power transfer between two independent power sources and ensure consistent energy delivery for essential loads.

## Overview of the ATS-CB021 Series

The ABB ATS-CB021 Series is a new generation of intelligent automatic transfer switches engineered to enhance power system reliability while simplifying operation and maintenance. It automatically monitors both the primary and backup power sources, and when a fault or power quality issue is detected—such as under-voltage, power outage, phase loss, or incorrect phase sequence—the switch rapidly transfers the load to the secondary source to maintain uninterrupted supply.

This series combines ABB’s extensive expertise in low-voltage systems with advanced monitoring and control technology, offering users excellent switching reliability, mechanical durability, and flexible configuration options for a wide range of applications.

## Fast, Safe, and Reliable Transfer Performance

One of the most prominent advantages of the ATS-CB021 Series is its rapid response during transfer operations. The device evaluates power source conditions in real time and executes switching instructions based on preset logic. Whether operating in automatic or manual mode, the transfer process is optimized for speed and reliability.

To ensure safety, the switch incorporates **dual protection interlocks**, including:

* Mechanical interlock
* Electrical interlock

This dual-safeguard mechanism effectively prevents simultaneous closure of both power sources, reducing the risk of back-feeding, short circuits, or unexpected faults.

## Intelligent Monitoring and Adjustable Control Logic

The ATS-CB021 is equipped with a sophisticated control unit capable of monitoring power parameters such as:

* Voltage and frequency levels
* Phase sequence and phase loss
* Over-voltage and under-voltage conditions

Users can configure switching priorities and timing to meet the requirements of different applications. Features include:

* Adjustable transfer delay
* Automatic re-transfer to primary power when normal conditions resume
* Flexible logic settings for source preference
* Fault detection and alarm output

In addition, communication interfaces support remote monitoring and management through a supervisory system, enabling real-time status display, event recording, and preventive maintenance strategies.

## Compact Structure and Easy Integration

Designed with modular architecture, the ATS-CB021 Series offers a compact footprint and flexible layout options for integration into switchboards, distribution units, motor control centers, and industrial automation systems. The unit’s installation is simplified through standardized mounting dimensions and clearly arranged terminals, reducing commissioning time and labor cost.

Its compatibility with various circuit breakers and low-voltage switchgear products makes it suitable for both new projects and retrofit applications, allowing engineers to implement upgrades without major structural modification.
