Structural Features
The entire cabinet features a modular, assembled structure with standardized, versatile components that are highly adaptable and easy to apply. It allows for flexible assembly into various structural configurations based on specific project requirements.
The electrical component room, busbar room, and feeder cable room are all individually isolated from one another, as well as from different circuits within the functional units, using steel or insulating panels that provide clear separation and ensure operational safety.

The components are securely mounted within the functional unit, and the circuit breakers are designed as either pull-out or plug-in types for easy maintenance and troubleshooting.
The functional unit's operating handle controls the switch between its on and off positions, and it can also be operated remotely using an external power source.
Fixed partition units require no plug-in connections, ensuring safety.
