SJKQ5 dual power automatic transfer switch 250A

Performance and Features
Adopting double row composite contacts, transverse pull mechanism, micro motor pre energy storage and microelectronic control technology, basically achieving zero arcing (without arc extinguishing hood)
◆ Adopting reliable mechanical and electrical interlocks, with independent load isolation switches for executing components, ensuring safe and reliable use
Adopting zero crossing technology, it can be forcibly zeroed in emergency situations (while cutting off two power sources) to meet the needs of fire linkage
The operator drives the motor to only pass current at the moment of switching the load isolation switch, and no working current is required for steady-state operation, resulting in significant energy savings
The load isolation switch is equipped with a mechanical interlocking device to ensure reliable and non interfering operation of the common and backup power sources
◆ It has obvious on/off position indication, padlock and other functions, reliably achieving isolation between power supply and load
Good safety performance, high degree of automation, high reliability, and a service life of over 8000 times
◆ Four operation functions: emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state, and automatic control operation
