SIRCOVER (I-0-II) BBM MTS

Function

SIRCOVER products are manually operated transfer switches with positive break indication. There are 3 ranges in the series:

• SIRCOVER for open transition switching (I-0-II) available in 3 or 4 pole,
• SIRCOVER for overlapping contact switching (I-I+II-II),

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. 

• SIRCOVER Bypass. This combination of three interlocked load break switches provides 3+6 or 4+8 poles for bypass applications.

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.
