Model and meaning

RP5D Dual Power Automatic Transfer Switch Series is a kind of new automatic transfer switch gathered with switch and logic controller，achieve mechanic and electricity turn into a integral whole. It is suitable for using in the distribution equipment in industry and business with rated insulating voltage up to 690V, rated frequency 50Hz/60Hz, rated voltage 380V, conventional heating current up to 3200A ,it is used to transfer automatically between Normal power and reserve power in power system or transfer automatically and safety isolation of two sets load device etc. It can be used for hospital, shop, bank, high building, coal mine, telecommunication, iron mine, superhighway, airport, industrial flowing water line and military installation etc. Important situation where disallow power supply failure.

The switch can achieve full-automatic, compulsory “0”, remote control, urgent manual-

operation; It also has the functions of lack phase examination and protection, electric mechanism interlock etc.

Product Features

◆Good safety:With double-row composite contact, levelly-pulling opening and closing mechanism, micro motor energy pre-stored technology as well as microelectronic control technology, it can basically realize no flashover (no arc chute)

◆Adopt reliable mechanical and electrical interlocking

◆Due to zero crossing technology, it can set to zero compulsorily under emergency (Cut off double circuit power synchronously)

◆With visible indication of on/off  position and padlocking function, it can get the space between power supply and load.

◆High reliability, service life reaching 8000 times

◆Being designed with electromechanical integration, the switch transfers accurately, flexibly and smoothly.Superior electromagnetism compatibility, strong capability to resist the interference,no interference to outside.

◆The switch has multi-circuit input/output interface that can realize PLC remote control as well as automation of system.

◆The switch needn't any external control elements.

◆Nice appearance, small volume, light weight.

◆The product conforms to following standards: GB/T 14048.11-2008/IEC60947-6-1 Automatic Transfer Switching Equipment, GB/T14048.3-2008/IEC60947-1 Low－voltage Switchgear and Controlgear General Rules as well as GB/14048.3-2008/IEC60947-3 Low-voltage Switchgear and Controlgear--Low-voltage Switches, Disconnectors, Switch-disconnectors and Fuse-combination units.
