Product overview
KYNl8A-12 indoor type alternating-current metal-clad withdrawable metal-enclosed switchgear (hereinafter referred to as switchgear) is a kind of mid-set vacuum switchgear. It usually uses ZN22B-12 vacuum circuit breaker as the vacuum switch,
also can be equipped with ZNl2-10 vacuum circuit breaker, or 3AF and 3AH vacuum circuit breakers from Siemens. It is
applicable for three-phase single-bus power systems of AC50HZ and voltage class 3-10kV, used for electric energy receiving
and distribution. It is widely used in power plants, substations, and industrial and mining enterprises. It can be installed against the wall (not recommended) or not against the wall.
It complies with GB3906-91 A.C. metal-enclosed switchgear for rated voltages of 3~35kV, DL404-91 Indoor AC high voltage switchgear panel, IEC298 Alternating-current metal-enclosed switchgear and controlgear, etc.
