Advantages

Reliability and performance

The double-breaking-per-pole design, achieved through its sliding bar contact system, is a proven design that offers very high durability and short-circuit withstand. Quick opening and rapid closure combined with cut-off chambers on SIRCO AC units delivers high breaking performance.

Safety of operation and personnel

The position indicator is located directly on the sliding bar contact mechanism, ensuring it can be seen in all circumstances.
The use of glass fibre reinforced polyester gives the SIRCO AC both high mechanical and thermal resistance.

Simplicity

The standardisation of the SIRCO AC range and its wide choice of common accessories enable:
- Simple mounting.
- Reduced stock management and storage costs.

Easy to install

The outdoor ranges are easy to install with:
- A good centre-to-centre distance (up to 120 mm).
- Connection up to 6 x 185 mm².
- Connection accessories for both flat and edgewise connections.
