SIRCOVER products are manually operated transfer switches with positive break indication. There are 3 ranges in the series:
For applications where both sources are synchronised and there is to be no interruption to the load supply during transfer - available in 3 or 4 pole.
They provide on-load transfer between two sources for any low voltage power circuit, as well as safety isolation by double breaking per pole. Other applications include source inversion (e.g. to change the direction of a motor) or grounding/earthing.
