Recloser Bypass Disconnects are used in combination with a separately mounted S&C Loadbuster Disconnect® Switch to bypass and isolate automatic circuit reclosers for maintenance or inspection. These station-type devices are also suitable for other applications, such as bypassing and isolating current transformers.

S&C Recloser Bypass Disconnects are available in voltage ratings of 14.4 kV, 25 kV, and 34.5 kV and, depending on which S&C Recloser Bypass Disconnect is specified, can be applied on circuits having a continuous current level through 600 amperes.

Recloser Bypass Disconnects consist of a fuse — an S&C Type SMD-20, Type SMD-40, or Type SM-5® Power Fuse, or an S&C Type XS Fuse Cutout (depending on the available fault and continuous current levels of the application) — in series with an integral S&C Loadbuster Disconnect. The fuse is inserted into the device to protect the circuit while the recloser is out of service.

Recloser Bypass Disconnects are alternately available with a second Loadbuster Disconnect (in place of the fuse) for applications where devices other than protective equipment are being bypassed for maintenance or inspection.

S&C’s Recloser Bypass Disconnects are manufactured in accordance with a quality system certified to ISO9001:2000.
