KZF 11 Thyristor Contactor
KZF 11
The KZF 11 thyristor contactor is designed for use in spot, seam, and projection contact welding machines and is used to switch and control single-phase industrial-frequency current when equipped with a control unit featuring synchronous welding current activation.
The contactor is controlled by synchronous welding controllers of the RKS-502, RKS-801, RKS-801M, and RKS-M types
