● The zero-bit technology, emergency situations can be forced to zero (and cut off two-way power), to meet the need for fire protection;
● Run load isolation switch with a single motor drives, switching stable and reliable, no noise, low-impact;
● Operating drive motor is switched only in the implementation of the current through the load isolation switch instantly, without providing steady work for the current master, significant energy saving;.
● Run load isolation switch with mechanical interlock devices to ensure common, reliable backup power noninterference;
● has clear-off position indicator, padlock isolation and other functions, to achieve a reliable power supply and the load between;
● good safety performance, high degree of automation, high reliability and service life of more than 8000 times;

eight, I type switch control features
● 100A of the following:
A, suitable for two-way dust Standby mains;
B, when the main power supply circuit malfunction (power failure or phase) switch after delay (can be set 1 ~ 16s) is automatically put into the standby power supply circuit.
C, when the mains supply returns to normal, the switch by the delay (can be set 1 ~ 250s) automatically switches back to the main power supply circuit.
● 125A above:
A, applicable to primary and secondary system two mains or mutual backup systems.
B, switch selected as the automatic recovery function (ie primary and secondary type). When the mains supply fails (power failure, phase), switching by the delay (can be set 1 ~ 16s) is automatically put into the standby power supply circuit; when the main circuit returns to normal, the switch by the delay (can be set 1 ~ 120s) Automatic Cut back to the main power supply circuit.
C, switch selected from a vote of no self-recovery capabilities (ie mutual standby type) ,. When I channel power circuit failure (power failure, phase); a switch by the delay (can be set 1 ~ 16s) automatically into II-way power circuit; when the power supply circuit II returns to normal, the switch does not cut back to the I-way. II road only when the power circuit failure; a switch only by the delay (can be set 1 ~ 120s) automatically cut the loop I-way power circuit.
● Priority power supply circuit terminal selection by the patch.
Nine, type II switch control features
● suitable for two-way mains standby system or mutual backup systems.
● switch selected as automatic recovery function, when the main power supply circuit malfunction (phase, over voltage) switch after delay (can be set 1 ~ 16s) from automatically into the standby power supply circuit; when the main circuit return to normal: switch by the delay (can be set 1 ~ 120s) automatically switches back to the main power supply circuit.
● switch to select the automatic switching when no self-recovery function, when the I-way power supply network failure (phase, over voltage); a switch by the delay (can be set 1 ~ 16s) automatically into the II-way power circuit; when When the I-way power circuit returns to normal, the switch does not cut back to the I-way, the road only when I power circuit fails, the switch only after delay (can be set to 1 ~ 120s) automatically switch back to I-way power circuit.
● Select priority power supply circuit (125A and above) through the terminal.
ten, III switching control features
● applies mainly to the mains power supply, standby generators powered systems.
● When the mains fails, the switch controller first sends oil machine start signal, after switching delay 3s, switch first to invest in "O" position, and then when Ting (warm-up time adjustable 1 ~ 250s) automatically into oil machine power supply circuit.
● When utility power is restored to normal. Switch by the delay (can be set 1 ~ 250s) automatically switch back to the mains supply, then delay (can be set 1 ~ 250s), the controller sends out a signal to close oil machine.
