The DOUBLE DECK SWITCHGEAR allows to reduce space by stacking two circuit breakers within the same compartment. This design significantly reduces the overall switchgear length by approximately 30%, optimizing space utilization in eletrical installations.
These metal clad units have a metallic structure in LSC2B-pM class, air insulated and ready to be equipped with interrupting devices in withdrawable execution.
Principal features of the MINIVER/C DOUBLE DECK
- Wide range of functional units
- Modular structure
- Internal arc version (if requested)
- Equipped with mechanical and electrical interlocks for maximum safety
- Compactness and optimization of the spaces
- Version with double outgoing in one cubicle available
- Can be equipped with any type of relay chosen by the customer (for example: ABB, Stucke, Siemens, Schneider Electric etc..)
- Also available with short circuit limiting devices such as ABB IS LimiterTM
- Certifications on type tests and acceptance tests available
With its features the MINIVER/C DOUBLE DECK range is ideal for offering solutions designed for being adapted to every type of applications, maintaining the continuity of service and safety for operators.
The flexibility of Medium voltage Double Deck switchgears make them suitable for several installations:
- Naval Cruise
- Navy
