SIRCOVER provide open transition switching (I-0-II), on-load transfer between two sources for any low voltage power circuit, as well as safety isolation with double breaking per pole. In addition to source changeover function, they can as well be used for source inversion (e.g. to change the direction of a motor) or grounding/earthing. They are availlable in 3 or 4 poles.
A complete range
The standard model I-0-II from 125 to 3200A.
Easy to connect
For ratings of 2000 to 3200 A, we offer copper bar connection pieces. This gives you the option of different connection methods: flat, edgewise with top or bottom bridging.
SIRCOVER devices have three stable positions, unaffected by voltage fluctuations and vibrations, protecting your loads from network disturbances.
With its AC-23 and AC-33 characteristics, tested according to standards IEC 60947-3 and IEC 60947-6-1, the SIRCOVER enables safe on-load switching for any type of load. With its on-load transfer capabilities, it is not necessary to isolate loads prior to transfer therefore the SIRCOVER offers an economical solution.
