What Is an Operation Box?
An operation box, often referred to as a control box, switch box, cabinet box, or enclosure, is designed for housing and organizing control equipment and operating switches. These boxes facilitate the remote control of machines, devices, or equipment from a location separate from the main control panel.
Uses of Operation Boxes
Operation boxes serve a wide range of applications, including:
- FA control boxes and switch boxes for industrial control equipment.
- Breakers, control units, and pull boxes for electrical power equipment.
- Storage boxes for terminal block and equipment in factory settings, facilitating power connections to machine tools.
- Base stations and outdoor access points for telecommunications equipment.
- Connection boxes for solar power generation, outdoor measuring instruments, and communication equipment.
These boxes typically accommodate input and display devices such as pushbutton switches, selector switches, indicators, programmable displays, and panel computers.
Principle of Operation Boxes
An operation box includes a main body and a cover that opens via screws or hinges. It mounts control devices for input and display on the cover, allowing operation and visibility even when closed. Inside, a mounting board may be present for attaching additional control devices like control relays and terminal blocks. Cable glands and through holes facilitate the connection of control cables.
Types of Operation Boxes
1. Classification by Structure
Operation boxes vary by their opening mechanism—fixed or retractable—and may include locking features or hand grips for easy adjustment. The size selection depends on the internal components and required cable management.
2. Classification by Material
Materials range from steel, stainless steel, aluminum casting, to polycarbonate and polybutylene terephthalate resins. The choice depends on the application environment, including indoor/outdoor placement and the need for protection against the elements.
3. Protection and Explosion-Proof Types
Operation boxes are classified by dust and waterproof grades (IP Code) and explosion-proof construction for hazardous locations. Selection should match the environmental conditions.
