This is for the relay and switchgear experts. I have been looking at the ABB "FT Flexitest" switches.

http://www.abb.com/product/db0003db004281/c12573e70033041985256ad20066cda8.aspx

They allow a user to isolate a switchgear relay and then perform tests. The FT means the user can disconnect relay inputs and outputs, then test relay operation without disrupting a facility.

For example, has a "make before break" way to disconnect CTs feeding a relay and safely ground secondaries of the CTs.

Considering using the FT to remove an arc-flash relay from service, for test and adjustment.

Am I on the right track?

I agree. I've used these in relay apps before. They are a quality product.
