# **ABB DPT-CB011 Automatic Transfer Switch: Ensuring Reliable Power Continuity for Critical Loads**

In today’s industrial and commercial environments, maintaining continuous and stable power supply is no longer optional—it is essential. Facilities such as hospitals, data centers, transportation networks, and automated production lines demand absolute reliability in electrical power. Any interruption or instability can lead to operational disruptions, equipment damage, data loss, or even safety risks. To meet these demanding requirements, ABB has developed the **DPT-CB011 Automatic Transfer Switch (ATS)**, a robust and intelligent solution designed to ensure uninterrupted power continuity for critical loads.

## **Overview of the DPT-CB011**

The ABB DPT-CB011 is a low-voltage automatic transfer switch system engineered to provide seamless switching between two independent power sources: a primary and an auxiliary power supply. When the main supply experiences a power outage, under-voltage, phase loss, or other abnormal conditions, the device automatically initiates a rapid transfer to the backup source. Once the main supply recovers, the DPT-CB011 can switch back to the primary source automatically or manually, depending on user settings.

With its integrated monitoring, protection, and control features, this transfer switch is widely applied in systems where power continuity is mission-critical.

## **Reliable and Fast Transfer Capabilities**

### **High-Speed Automatic Switching**

One of the core strengths of the DPT-CB011 lies in its rapid response to power anomalies. The controller continuously evaluates voltage levels, frequency, and phase conditions of both power sources. When it detects a disturbance or outage, it triggers an immediate transfer, minimizing downtime and protecting sensitive loads.

### **Dual Mechanical and Electrical Interlocks**

To prevent simultaneous connection of the two power sources, ABB incorporates both mechanical and electrical interlocking. This dual-layer protection ensures that only one source can be connected at any given moment, preventing dangerous short circuits and enhancing system safety and reliability.

These features make the DPT-CB011 exceptionally trustworthy for critical applications.

## **Advanced Monitoring and Control Functions**

### **Comprehensive Power Condition Monitoring**

The integrated controller offers real-time monitoring for:

* under-voltage
* over-voltage
* phase loss
* frequency deviation
* incorrect phase sequence

This ensures switching occurs only when the backup source is stable and suitable, reducing false transfers and protecting downstream equipment.

### **Flexible Operating Modes**

The switch supports:

* **automatic mode** for unattended operation
* **manual mode** for maintenance and commissioning
* **remote mode** for integration with supervisory control systems

This level of flexibility allows customization according to different project needs and operational strategies.
