SIRCOVER AC are manual multipolar transfer switches with positive break indication. The family includes three ranges:
• SIRCOVER AC for open transition switching (I-0-II),
• SIRCOVER for overlapping contact switching (I-I+II-II), and
• SIRCOVER Bypass. This version is a combination of three interlocked switches enabling use with 3 + 6 poles or 4 + 8 poles.
They provide switching, source inversion and transfer under load for two low voltage power circuits, as well as their safety isolation by double breaking per pole.
Advantages
A complete product range
Three versions of the SIRCOVER are available to ensure compatibility with the maximum number of applications: SIRCOVER AC
(I-0-II) with improved on load switching characteristics and isolation position, SIRCOVER with overlapping contacts (I-I+II-II) and a BYPASS version.
Easy connections
A copper bar connection kit is available for 2000 to 3200 A ratings. It enables various types of connection: flat or edgewise connection with top or bottom bridging.
Stable positions
SIRCOVERs have three stable positions which are not affected by voltage drops or vibrations, thus protecting your load against network interference.
Improved on load switching
Thanks to its AC-23 and AC-33 characteristics, which are tested in accordance with standards IEC 60947-3 and IEC 60947-6-1, the SIRCOVER AC enables secure and reliable switching on all types
of load, without the need for pre-breaking upstream.
