Composite switch

*Performance characteristics

Advanced software zero crossing detection technology can accurately find out the zero crossing. Unique capacitor discharge technology, reliable protection of capacitor and composite switch life. Key components are high-end industrial devices, and have authority certificate.

Special treatment has been made for power on and power off to prevent the thyristor from mistakenly triggering when power on or the capacitor cannot be cut off in time when power off.

*Technical specifications

Product series: wfk-3d series; wfk-2d series; three phase compensation rated current: common 45, 55, 70, 80A. Rated current of split phase compensation: 45, 55, 70, 80A in common use.
