Advantages

High-performance switching

SIRCO DC load break switches include a patented technology providing 1500 VDC breaking capacity with only 2 poles, with significant power loss reduction. This range covers nominal values from 2000 to 3600 A, 1500 VDC.

Design tested in application

Designed and tested for numerous direct current applications, with tried-and-tested performance in the most difficult environments. The arc quenching system provides safe disconnection, arc quenching and quick current interruption.
- Tested against high short-circuit systems with and without fuse protection to provide complete protection for the system above 210 kA.
- Tried-and-tested against severe environmental factors, in particular: “Annex Q level C according to IEC” tested in salt mist, at high temperature and altitude, tested in humidity cycle.

Reduced total cost of ownership

Developed with a view to reducing costs for the user, the product has improvements that ensure the lowest total cost of ownership.
- Flexible connection configurations enable simple input and output connection, with savings made by not using bridging bars in series.
- The multi-circuit design enables configuration of one 3600 A circuit or two 1600 A circuits for greater flexibility.
- A single design for IEC and UL products provides the same base design for customers with IEC or UL machines.
- A compact solution with reduced footprint and weight improves the durability, while reducing packaging, transport and installation costs.
