Overview for KZN1 (KYN28A)-12 Metal-clad AC Switchgear, for indoor
General of KZN1 (KYN28A)-12 Metal-clad AC Switchgear, for indoor
KYN28A-12 Metal-enclosed Separate Type Switch Facilities is a In-door Power Distribution System of AC 50Hz, Three Phase, with Single Busbar or Double Busbar, for the use of Connecting and Distributing 3-10Kv Net-Power, and to protect, control and monitor the Electric Circuit.
Working conditions of KZN1 (KYN28A)-12 Metal-clad AC Switchgear, for indoor
a. The Ambient temperature upper limit and lower limit are
respectively +40°C and -40°C; (allowing storage and transportation
at -30°C);
b. Altitude is not more than 1000m;
c. Relative humidity: daily average value should not be more than
95%, while monthly average value should not be more than 90%

corrosion and violent vibration.
Product features of KZN1 (KYN28A)-12 Metal-clad AC Switchgear, for indoor
(1)The body structure is spliced with AI-Zn-plated steel sheet, which underwent repeated edge forces.
(2)All equipment can be operated when the cabinet door is closed.
(3)The cabinet housing is fully sealed to prevent sundries and pests and its protection degree is IP4X. Besides, the protection degree of handcart compartment, busbar compartment, cable compartment and relay instrument compartment is IP2X.
(4)Simple and effective locking can prevent misoperation. The perfect "five-anti" interlocking device provides reliable safety protection for equipment operators.
(5) The circuit breaker can be replaced in a quite simple manner with interchangeable handcarts. VT19 and imported VD4 vacuum circuit breaker are provided.
(6) The vacuum circuit breaker and its operating mechanism in the high-pressure compartment need only a little maintenance.
(7) The cabinet can be installed against the wall to save space.
(8) The secondary line is fastened in the wiring duct of large size, which is easy to connect.
(9) The mid-set structure provides large space for the cable compartment connected to multi-cables.
(10) The installation of cable compartment can be easily observed through the panel inspection window.
(11) The cable compartment and secondary instrument compartment are independently fitted with grounding busbar with good contact with the cabinets.
