Principal Application: Recloser Maintenance
By design, the BP3 Switch provides an economical means for bypassing and disconnecting a pole-mounted distribution recloser. This permits de-energized periodic maintenance of the recloser without interrupting service. The BP3 Switch accomplishes this by a combination of three disconnect switches mounted on a common base. By operating the blades in proper sequence, the recloser is bypassed and isolated from the distribution system.

Operation
Figures below illustrate the BP3 Bypass Switch operation. In normal operation, the bypass switchblade is open and the two disconnect blades are closed, allowing the recloser to be in the circuit.
When recloser maintenance, testing, repair or removal isrequired, first close the bypass blade to provide a parallel current path. Then open the recloser’s internal contacts. And last, open both disconnect blades of the bypass switch. In this way, service continuity is maintained and the recloser is isolated from the line. To put the recloser back in service, the switch operating procedure is reversed.
