Supply, outgoing and coupling cells are equipped with SENTRON® 3WL air circuit breakers in stationary and withdrawable technology, or alternatively, with SENTRON 3VL compact circuit breakers. Because many receivers are generally installed on the line downstream these circuit breakers, they are extremely important in ensuring long-term operational safety of the switchgear and personnel safety. SIVACON compactly and safely meets the above requirements through the components of the circuit breaker system.
Universal installation system
Because many applications require a space-optimized assembly of the power distribution switchgears, different installation systems must be integrated in one cell. For such applications, the universal SIVACON assembly system ensures high performance, safety and diversity due to the combination of outgoing feeders in withdrawable, plug-in, stationary techniques and outgoing feeders in the 3NJ6 pin strip technology. What’s more, the withdrawable technique provides significant flexibility with often varying requirements such as variable motor parameters or connecting new receivers. In addition, this technique also meets ergonomic requirements and facilitates simple and safe operation, as well as short set-up times for maximum system availability.
Busbar

Universal Installation System
Individual Combination Options (Fixed-Mounted Design with compartment doors, Plug-In 3NJ6 In-Line Design).
Many applications require different solutions suitable for different protection systems, therefore different installation systems must be integrated in one cell. For such applications, the universal SIVACON mounting system ensures high performance, safety and flexibility due to the combination of outgoing feeders in fixed-mounted design and in plug-in 3NJ6 in-line system.
More details can be found in the catalog card below in the tab.
Fixed-Mounted System with Front Covers
Wide integration options
- High system safety due to standard modules with type testing.
- Cable feeders up to 630 A with and without current measurement.
- Modularly combined functional groups.
- The innovative quick fastening system allows easy mounting of the cover.
- Hinged frame with covers for easier supervision and ease of maintenance.
- Expansion modules when functional separation of compartments is required (up to form 4b).
- Front control panel with covers, optionally with full cell door height.
- Doors with an inspection window enabling integration with modern interiors.
