ZW10-12 series outdoor high-voltage dual power automatic switching device (Hereinafter referred to as device) composed of High-voltage vacuum circuit breaker and intelligent controller. Widely used for AC 50 Hz, rated voltage 12kV, rated current 630A dual power supply system.

 

As one circuit outage or under-voltage automatically switch to other normal power supply to reliably ensure the continuity of power. The protection and interlock for short circuit and over current effectively avoid unnecessary re-loading power failure impact. In the commonly used power outage power failure, the switching device can automatically switch with the backup power supply to ensure the reliability and security. According to needs of load, automatically switch between two circuits. As important electrical control devices, especially used for important place which does not allow power failure ensure a continuous power supply.

 

This product which is dual power supply with automatic-recovery & automatic-switching has more advantages such as new generation of innovative, safe and reliable, performance improved, high degree of automation, wide usage and so on.       

 

Products designed for ensuring complete isolation of dual high-voltage power supply, with sound and reliable mechanical and electrical chain, it has a very high safety and reliability. The product is suitable for dual supply system control users who required strictly reliability and security, as controller and protector of the dual power supply system.
