Model Meaning
Functions and Features
◆Cabinet body is welded with high-quality angle steel.
◆The circuit breaker room is located in the middle (lower) part of the cabinet, which is convenient for installation, debugging and maintenance. Standard equipped with VS1 circuit breaker, and has a pressure release channel to ensure personal safety.
◆Adopt advanced and reliable rotary isolating switch, which can safely enter the circuit breaker room for maintenance when the main bus is live.
◆The protection grade of the whole cabinet is IP2X.
◆It is equipped with a reliable and complete mandatory mechanical locking device, which can easily and effectively meet the requirements of “five preventions”.
◆Have a reliable grounding system.
◆The door is equipped with an observation window, which can clearly observe the working state of the components in the cabinet.
◆The locking mechanism of the operating mechanism adopts the same JSXGN locking mechanism used in the XGN2-12 cabinet, which is simple, reliable, convenient and practical.
◆Incoming and outgoing cables are lower than the front of the cabinet, which is convenient for users to connect.
