Automatic transfer switch RDS3 series

4-pole3-pole

Application RDS3 Series PC class dual power Auto transfer switch, mainly used in two way power supply system with rated voltage below 400V, AC 50/60Hz, rated current up to 630A, when one power supply abnormal, then it transfer between two power supply system, to ensure the power supply reliablity and safety. The ATS have " Main Power", "Backup Power" and "Two way OFF" positions, with higher breaking and making capacity, it not only can meet normal load transfer, but also can meet high inductive impedance or big motor load transfer, meanwhile due to have high short time withstand current capacity, no need special SPCD, doesn't affect the selective of inside circuit, meanwhile it also can meet the application at big capacity power supply side. Product confirm to GB/T14048.11《Low voltage switch equipment and control equipment Part 6-1: multi-funtional transfer switch equipment》 Standard. Working Conditions • Ambient température: -20rC -+40rC ; 24hours average not more than +35X) ; • Atmospheric conditions: humidity not more than 50% at max. +40"C , higher humidity is allowed at lower température, at most wet month, the average max humidity is 90% at the average min température +25*C, and hâve considered the condensation on the product surface due to température variation; • Altitude: Not more than 2000m; • Pollution Class: The installation site environment pollution Class 3. Product Features • High short time withstand capacity, high short circuit making capacity Adopt high density silver alloy contact, can withstand thousands operating cycles and no burning loss, no pit or no melting. No need daily contact maintenance, 100% rated current continues load.
