Efficient and energy-saving, with low temperature rise
SIWOKB1 adopts advanced energy-saving technology for control and protection of switch electrical appliances. The switch electromagnetic system adopts a starting current circuit and a switch holding current circuit. The switch electromagnetic system is AC started, and the DC holding and closing working mode controlled by a microcontroller reduces the consumption of the switch electromagnetic system and short circuit ring, reduces the copper loss of the coil, saves electricity, and reduces the temperature rise and noise of the switch electromagnetic system.
Reliable performance and long service life
The electromagnetic system of SIWOKB1 control and protection switch appliances has added a buffer device to reduce the energy impact of the switch electromagnetic system, thereby improving the suction performance of the switch and extending its service life. SIWOKB1 control and protection switch appliances use high-quality industrial grade microcontrollers and branded electronic components in the field of microelectronics, with carefully designed circuits that optimize the design from both software and hardware aspects to reduce electromagnetic interference and improve product reliability.
Flexible installation
Users can select functional modules or accessories according to their needs to achieve control and protection of various motor loads and distribution loads.
Horizontal installation, vertical installation, and horizontal installation do not affect the performance. 45 shell frame products can be installed on sliding rails or fixed.
