When decouplers are installed on a pipeline for AC voltage mitigation and over-voltage protection, there may be occasions where disconnection of the decoupler is required. Safe disconnection cannot always be easily accomplished by hand if notable AC induction is present, therefore Dairyland designed the Isolation Switch to serve this need. Where such isolation is necessary, the Isolation Switch allows safe disconnection without causing exposed arcs, in an AC fault-rated design.
The Dairyland SWX-100 Switch Kit for the MTP-48 consists of the SWX-100 pull-style isolation switch, a 2/0 AWG lead assembly and all mounting hardware needed to install the switch in an MTP-48 pedestal for use with any Dairyland decoupler. The MTP-48 and decoupler are sold separately.
