1/Principle

1. CB-class automatic transfer switch is an electronic product that converts one or more load circuits from one power source to another.

2. PC-class automatic transfer switching appliances are appliances that convert one or more load circuits from one power source to another. Automatic Transfer Switching Appliance (ATSE): An appliance that consists of a transfer switching device and other necessary appliances for monitoring power circuits and automatically converting one or more load circuits from one power source to another.

2/Advantage

1. CB-class transfer switch appliances, two circuit breakers are used as current breaking units, and are equipped with current release devices, which have certain protection capabilities. The on/off capacity of circuit breakers is much higher than that of relays.

2. The PC grade adopts the acceleration mechanism of spring energy storage and instantaneous release, which can quickly connect, break or convert circuits, and the product has reliable operation performance.

3/Design selection points

1. The indicators that need special attention when selecting CB-class transfer switch appliances are: the rated short-circuit making and breaking capacity of CB-level ATSE. In principle, the ATS automatic transfer switch is not used as a short-circuit protection device, but only as a power automatic transfer switch. The rated current of the ATSE should be greater than or equal to the setting current of its upper air circuit breaker.

2. The PC class determines the switching method according to the nature and different uses of each power supply: according to the nature of each power supply, the priority power supply is designated, and the priority power supply is not designated; and related functions such as overvoltage and undervoltage detection, frequency detection, phase loss detection, communication interface, electrical and mechanical interlocking, continuously adjustable delay conversion, etc. can be determined. Realize automatic, remote, emergency manual control, etc.
