Circuit breaker system

Circuit breaker system - Extremely friendly operation

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

Universal installation system - Individual configuration options (withdrawable, plug-in technology)

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

The plug-in busbar system is located at the back of the cell. It provides touch protection without any additional covers for active parts.

  • Installation resistant to electric arc.
  • Phase separation.
  • 3- and 4-pole technique.
  • Touch protection (IP20B).
  • Connection holes in the 50 mm modular grid for mounting standard withdrawable units.
