Horizontal Circuit Switchers

The most versatile and capable Horizontal Interrupter Circuit Switchers in the marketplace today (CSH, CHS-B).

The Southern States CSH and CSH-B horizontal interrupter circuit switchers are ideally suited for transformer protection on systems with fault currents up to 40 kA. All circuit making and breaking operations are accomplished in SF₆, eliminating open air arcs. The horizontal interrupter circuit switcher is available with (Model CSH-B) or without (Model CSH) an integral vertical break switch.

The design of the CSH and CSH-B is extremely versatile as they can be mounted in most any orientation including horizontal upright and vertical. They can also be designed to mount on a Southern States supplied support structure or for mounting on a customer supplied or existing structure. The CSH-B is ideal for mobile applications and can be supplied with composite interrupters that allow for pressurized transport without special protective housing.

In addition to transformer protection, the CSH and CSH-B can be used for line dropping, loop splitting, or as a series capacitor/reactor bypass switch.
