“It is 3 a.m. and I get the call — a storm took down a pole outside of a substation and all three phases are on the ground. We have a lot of members out of service and want to make repairs quickly. “ Before we can make those repairs, we need a visible opening on both sides of the fault. At the substation, the line/ load switches are locked open, so we are good there. Down-line is a set of three electronic reclosers, but their contacts are internal. “So, how do we get our visible opening?”

The BP3 simplifies the isolation/by-pass-switch configuration for three-phase reclosers and for three single-phase reclosers installations.
