Hello Bill.. The breaker is recommended only for use with a non-TenTec
supply or battery (page 2-1 of my Corsair-2 manual).
The 961's fuse is on the AC side of the power supply, for power supply
protection against internal component failure or gross overload.
The over-current circuit is on the output side of the supply, and reacts
much faster than the AC line fuse could to protect the Corsair PA. Check out
the manual pages 2-13 thru 2-16 for interesting info about Ten Tec designs
and why they need the fast over-current protection.
