what does protect circuit mean?

[west33637]

Hello all. I've been hearing this terminology used loosely for years. I think I know what it means, but would like to be clear. What does protect circuit mean? What does the term 'switched to protect' mean? Thanks,

Protected refers to the redundancy of the circuit.
