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.The main technical parameters
