Usage:
The equipment is suitable for the electric network, which has the rated operation voltage of 400V, operation current of 3600A or below, frequency 50Hz A. C. And used as power lighting, electric energy transforming, protecting and controlling in the system of electricity generation, transmitting and distribution.

Sturcture Feature:
1. The frame of switchgear equipment are made of C-shaped bar section with modular holes which are arranged at intervals of 25mm. The bar section has been zinc-plated and passivated (or the steel plate coated with aluminum and zinc can be used alternatively. ) The basic frames are assembled with the C-shaped bar section using self-tapping screws or high strength bolts.
2. The body of switchgear could be divided into the function compartment, the cable compartment and the bus-bar compartment, each one is separated by the fire resistant engineering plastic piece or steel plate.
3. frames and drawer units compose different types of combination. The drawer units possess features of compact size, high performance, good interchangeability, easy maintenance and reliable contacting etc.
4. There is L-shaped copper busbar in the switchgear. It is inlaid in the function partition wall, which is made of fire resistant engineering plastics. The protective grade of the electrified part reaches IP2X.
5. There is reliable mechanical interlocking device inside drawer units. The mechanical interlocking device makes drawer units possible to be on three obvious positions of connection, test and separation. The handles of mechanical interlocking device and breaker could be locked by padlock simultaneously.
