DESCRIPTION
The ATS-125A changeover switch is designed to automatically transfer load circuits from main power source to reserve source in a wide variety of 1-3 phase applications.

FEATURES
 Solenoid activated fast switching;
 1-3 phase 4 pole operation;
 High reliability due to stable positions of the change-over mechanism energized during switching process only;
 Front side position indication pointer and external lamp outputs;
 Built-in mechanical and electrical interlocking;
 Simple connection without external jumpers.

TECHNICAL SPECIFICATIONS
 Voltage: 230/400V(2-3 phase), 230V (1 phase), 120/208V(3 phase), 120/240V (2 phase).
 Voltage frequency: 50/60Hz.
 Switching poles: 4
 Phase current: up to 125А
 Working temperature range: от -5'C до +40'C
 Humidity: up to 50%
 Installation type: vertical
 Switching current: up to 3.5A
 Switching time: 200 ms
 Weight: 4.2 kg

INPUTS AND OUTPUTS
 Normal source inputs: R, S, T, N;
 Reserve source inputs: R, S, T, N;
 Load cirquit outputs: R, S, T, N;
 External indication lamp outputs.

OPERATION
Device monitors normal and reserve source phase voltages (internally connected to T and N terminal pairs).
In case if there is the normal source phase voltage, the device connects the load circuits to the normal power source inputs.
If the normal source phase voltage is lost, the device comes to a waiting mode keeping the load circuits connected to the normal power source inputs.
In case if there is the reserve source phase voltage (while normal source phase voltage is absent), the device connects the load circuits to the reserve power source inputs.
If the reserve phase voltage is lost, the device comes to a waiting mode keeping the load circuits connected to the reserve power source inputs.
