1. Prodcut Overview
Jcs9 series Automatic transfer switch mainly used for distribution or electromotor network, which under voltage 380V, rated voltage DC 220V, Rated current 16A-3200A.
Main power and standby power or mutual standby power change over system or city power and generator group overload switch-over. At the same time, it can operated under un-frequency on and off circuit act as disconnector.

Widely used at the field of important power supply site, which transport, distribution power supply system and automatization system. For fire protection,hospital,bank,building, etc, where doesn't allow power off.

2. Function: 
Full-automatic: i.e. Auto-switch-in, auto-restoring. When Normal power is off, switch will transfer to reserve power automatically;when Normal power is normal, switch will transfer to Normal power.
Compulsory "0": Under urgent situation or device examination,push compulsory "0" self-lock button,switch will transfer to position "0" to cut off both normal power and reserve power.

With generator: when normal power cut off, send out the starting signal of generator, to make generator starting automatically.When normal, the switch will transfer to generate electric automatically.When normal power comes normal, the switch will turn to normal power automatically.Meanwhile send out closing signal of generator, thus closed generator.
