Features

1. The operation and control handle of the drawer are combined into one, simplifyingthe operation while retaining the mechanical interlocking function. This overcomes the drawbacks of complex operation and susceptibility to damage in traditional MNS cabinets due to possible misoperation.
2. The MCC units are available in various combinations, compact in structure, and the cabinet can share back-to-back arrangement of busbars. Each cabinet can accommodate up to 36 circuits.
3. The cabinet can be arranged back-to-back or against the wall, saving installation space.
4. Standard components are used throughout, making it convenient for engineering designers.
5. The entire series is standardized, with strong structural versatility and flexible assembly.
6. A single cabinet can accommodate more units and can be freely combined into different types, such as fixed partition type and drawer type. Drawer units of the same specifications can be easily interchanged.
7. Stable combination performance and good grounding continuity.
8. High continuity and reliability of equipment operation.
9. The product has passed earthquake resistance, salt spray, and EMC electromagnetic compatibility tests, ensuring safe and reliable operation

Switchgear type

Power Center Cabinet
It adopts fixed installation withdrawable switches with various high-breaking capacity ranging from 630A to 630A, featuring advanced and intelligent circuit breakers.
Drawer type
Assembled with drawers of different sizes, each circuit’s main switch adopts high-breaking capacity plastic case circuit breakers or l oad switches with rotary-type fuse.
Fixed type:
MCC cabinet (Motor Control Center cabinet) functional units are assembled using plug-in plastic case circuit breakers, offering distinct breaking points and advantages such as enhanced safety and reliability.
Drawer/Fixed type:
There are five standard sizes, all based on a height of 8E (200mm).
8E/4: Assemble 4 drawer units in an 8E height space.
8E/2: Assemble 2 drawer units in an 8E height space.
8E: Assemble 1 drawer unit in an 8E height space.
16E: Assemble 1 drawer unit in a 16E (400mm) height space.
24E: Assemble 1 drawer unit in a 24E (600mm) height space.

Five types of drawer units can be assembled in a single cabinet or as a mixed assembly. The maximum number of fixed units for a single assembly in a cabinet is shown in Table 1
