Product Introduction：

KYN28A-12 High-voltage metal-clad withdrawable  switchgear is a complete indoor distribution device for three-phase AC 50Hz. It is used to receive and distribute 3.6-12 kV network electrical energy, and to control, protect and detect the circuit. This switchgear meets the requirements of standards such as GB3906, DL404, and IEC298, and has five anti-malfunction functions, namely preventing the circuit breaker from malfunctioning, preventing the load-bearing handcart from being pushed and pulled while it is energized, preventing the closing of the grounding switch while it is energized, preventing the grounding switch from supplying power while in the grounding position, and preventing accidental entry into an energized compartment. It can be equipped with both ZN63A (VSI) vacuum circuit breaker and imported VD4 vacuum circuit breaker.

Product Features：

1.The cabinet structure is assembled by multiple bending of aluminum-zinc plate.

2.Fully metal armored and thoroughly separated.

3.All equipment can be operated with the cabinet doors closed.

4.Simple and effective locking system to prevent accidental operations.

5.The cabinet has a high level of sealing to prevent foreign objects and pests from entering the equipment, with a protection class of IP4X.

6.The cabinet can be equipped with ZN63A (i.e., VSI) and imported VD4 vacuum circuit breakers.

7.Replacing circuit breakers is very simple with good interchangeability and compatibility with hand trolleys.

8.The cabinet can be reliably wall-mounted and allows for front maintenance, reducing the footprint of the equipment.

9.The secondary wiring is laid inside spacious wire ducts, making it easy to connect the wires.

10.The cable compartment has ample space and can accommodate multiple cables for connection.

11.Through the panel door, it is very easy to observe the installation of cables in the cable compartment.

12.The quick grounding switch is used for grounding and short-circuiting of the circuit.

It meets the relevant provisions of the GB/T11022-1999 "Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards", and is able to withstand the tests for condensation, pollution and humidity.
