Automatic Transfer Switch Structure and features
□ Reliable mechanical interlock between the two circuit breakers and electrical interlock device. Eliminate the two devices closing completely at the same time.
□ SCM intelligent controller used to control the core hardware is simple and powerful, expansion of convenience, high reliability.
□ It has a short circuit, over load protection functions, over voltage, under voltage, loss phase automatic transfer function andintelligent alarm function.
□ Automatic switching external parameters can be set free.
□ Operation of Intelligent motor protection
□ The control circuit devices with fire, fire control center to a control signal into intelligent controller. Two sets circuit breaker will enter a stating of breaking .
installation and dimension The main technical parameters
□ There is a computer network interface for achieving remote control four remote telemetry functions Product Model and Meaning
split type ATS can match W2,W3 type controller
Details of the controller please refer to page 37 to 45 Appearance and installation dimensions
Main technical data
Installion and wiring
□ Connect the linewire loadwire and neutral wire of normal power and ready power according to design of circuit must put the steel base through to earth for the sake of safety.Two breaker's terminal can be multipled, but must keep in phase.
□ Connect the neutral wire of circuit breaker of normal power and ready power with terminal of controller.
□ Controller can not working reliable if Cross-Sectional Areas of wire>=2.5mm
□ The operate handle as using for emergencies set it to the side of transfer mechanism using it after put the off button be necessarily,For the sake of observe for convenience Customer can connect a light to the terminal.
□ Connection as below circuit diagram
□ The connecting diagram is suitable for 4 phase ATSE. When use 3 phase ATES system,the Main power (NN) is connected to the junction foot N1 and the reserve power (RN) to the junction foot N2.
□ HD main power supply external status indication AC220V/1A (provided by user);
□ TD backup power supply external status indication AC220V/1A (provided by user); YESDLS series manual mechanical interlocking
Function and feature
YESDLS series manual mechanical interlocking is made up of two units in 3 pole and 4 pole of MCCB and the mechanical interlocking installed on the same base,and Composed of dual power switch and reliable manual chain mechanical interlocking.
