JJ1B auto decompression starter control cabinet series 
 Protection for the box-type structure, the auto-transformer, circuit breakers, AC contactors, thermal relays, current time converter, relay, ammeter, switches, buttons and lights and other components. Work with manual, automatic, remote control three, by the switch to switch. Remote control with input terminals, remote control operations to prepare for use. Autotransformer with rated voltage of 65% (60%) and 80% two-tap connected to the factory 60% of the tap, such as motor starting torque may require a larger change received 80% of the tap position, can also be received when ordering the wiper position. Products for more than 90KW, silent operation with energy saving devices can save energy, reduce noise, energy-saving devices controlled by the main switch can be manually input or removal.

 Second, the product description: 
 JJ1B series starting from the lotus root decompression control cabinet for the frequency 50HZ (60HZ), voltage 380V or 660V, power 11-320KW three-phase squirrel-cage induction motor for lower voltage, high current output to help motor starting, and acceleration motor to rated speed and to stop man-made motors, you can easily start the motor and overload, phase loss, short-circuit protection. In the starting process can also improve large motor starting currents impact on power and influence. This product is widely used in machinery, petroleum, chemical, electric power, coal, metallurgy, and other fields.
