CT1 and CT2

lyledunn

The connection of SPDs using CT1 appears to provide protection only in common mode. That seems be the normal method employed. However, looking at CT2 am I correct in assuming that the clamp voltage would need to be very much less as the protection is provided across the conductors supplying load components? It seems to me that CT1 is for lightning and CT2 more for overvoltages derived from switching???

    To be certain you need to remove the cartridges and use a multi-meter to "buzz out" the cross;links between the various devices.

    I'd hope Hagar knew their own product but that is how I'd verify it.
