MNS 1.0 adopts modular design, compact structure, flexible installation, and has multiple solutions such as circuit breaker technology, fixed installation technology, draw-out technology design and free combination design. It has passed the 3C type test, seismic test and internal arc test and obtained the first report. Currently, it is one of the more widely used cabinet types in low-voltage power distribution systems.
1.25mm modulus C profile, strong structural versatility, flexible assembly; Self-tapping locking connection with high continuity of ground protection; Five standard size drawers: 8E / 4, 8E / 2, 8E, 16E, 24E; The total height of the functional unit compartment is 72E, and a maximum of 36 8E / 4 circuits can be installed. There are galvanized metal bottom plates with ventilation holes between the upper and lower drawers to isolate them; The mechanical interlocking device ensures that the drawer can be moved only when the main circuit and the auxiliary circuit are all disconnected; With moving, testing, breaking, connecting and separating positions, and marked with corresponding symbols;
