◆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.
