双电源转换开关（PC 级和 CB 级）
应用场合
ABB双电源转换开关具有安装方便、使用简单、性能可靠等特点，主要适用于对供电可靠性、连
续性要求高的重要场合，避免因突然停电可能导致的各种严重问题或损失。如：高层建筑、机
场、医院、消防、数据中心、冶金、化工、电厂以及工业生产线等。
双电源转换开关分为PC级和CB级两个级别。
PC级双电源
PC 级采用隔离开关作为执行机构，能够接通和承载但不能分断短路电流，当负载过载时仍可保
持供电连续性。
PC 级双电源转换开关的应用：
• 手动式 — 用于通讯基站、电厂交直流分屏
• 电动式 — 用于柴油发电机
• 自动式 — 用于建筑项目的配电、照明、消防等场合
CB级双电源
CB 级采用断路器作为执行机构，配备过电流脱扣器，自身具有对负载侧用电设备和电缆的过载
保护功能，能够接通、承载和分断短路电流，当负载出现过载或短路时断开负载。
CB 级双电源转换开关的应用：
• DPT-CBmdash; 用于建筑配电、照明、消防等非重要负荷场合
• ATS配合 Tmax 或 E / F 开关）— 用于工业市场 （如：冶金、石化、电厂
等）、高铁和铁路项目等场合
• ATS022 也可用于带母联的场合

Dual power switch (PC and CB)
Application occasion
ABB dual power switch has the characteristics of convenient installation, simple use and reliable performance. It is mainly suitable for reliability and connection of power supply.
In important occasions with high continuity requirements, avoid all kinds of serious problems or losses that may be caused by sudden blackouts. For example: high-rise buildings, machinery
Field, hospital, fire protection, data center, metallurgy, chemical industry, power plant and industrial production line, etc.
Dual power switch is divided into PC level and CB level.
PC Class Dual Power Supply
PC level uses disconnector as actuator, which can be connected and loaded, but can not break short-circuit current, and can still be guaranteed when the load is overloaded.
Continuity of power supply is maintained.
Application of PC Class Dual Power Supply Conversion Switch:
Hand-operated - AC/DC split screen for communication base station and power plant
Electric - for diesel generators
- Automation - for distribution, lighting, fire protection and other occasions of construction projects
CB Class Dual Power Supply
CB class uses circuit breaker as actuator, equipped with over-current tripper, which has overload on load side electrical equipment and cables.
The protection function can turn on, load and break short-circuit current, and disconnect load when overload or short-circuit occurs.
Application of CB Class Dual Power Supply Conversion Switch:
• DPT-CBmdash; 用于建筑配电、照明、消防等非重要负荷场合
ATSwith Tmax or E/F switches) - Recommended for industrial markets (e.g. metallurgy, petrochemical, power plants)
On occasions such as high-speed rail, railway projects, etc.
ATS022 can also be used in occasions with bus Federations
