RDS2-630 Bypass Isolation Transfer Switches
Default ATS wiring terminals design is top input and bottom output (load). We provide an option to overturn ATS’s input and output load copper bars, flexible mounting at 250A – 630A. Below pictures to illustrate. Note: If customer need overturned input and output terminals, please specify at ordering.
Below is an example of 630A Automatic Transfer Switch overturned input with output wiring terminals.
Regular 630A ATS terminals
Overturned 630A ATS terminals

New features upgraded on RDS2-E:
1. ATS Transfer to "0" position when I or II power both failure. On the condition that A phase is normal, B or C phase loss, over or under voltage, over or under frequency, note, if A phase loss, this function not available, ATS must have power supply to enable it’s motor operation.
2. Fault event log.
3. Optional L module: Over load (current) protection, need to install additional CT go out of ATS. Threshold settable. This is another cards, please specify at ordering.
Reliable mechanical interlock device and electrical interlock protection, avoiding two MCCB closing at the same time; Controller power supply and power source sampling power are separated from SCM control system, effectively overcoming EMI from the hardware design;
Controller is removable, and can be installed separately, meet different installation requirement;
