LIMITED WARRANTY
Southern States, LLC (“SSLLC”) warrants only to the Warranty Holder (hereinafter defined as the “End
User” or the “Immediate Purchaser”, as applicable, pursuant to the terms and conditions of this Limited
Warranty as set forth below), that the Product identified below will, upon shipment, be free of defects in
workmanship and material for the applicable Warranty Period. The “Warranty Period” is that period of time
during which this Limited Warranty is effective, and such period begins on the invoice date issued by SSLLC
for the Product, and continues until the earlier to occur of (1) the expiration of the Warranty Duration period,
or (2) the Number of Operations, both as specified in the table below. If the Product is both purchased and
installed within the United States or Canada, this Limited Warranty is granted to each end user of the
Product who acquired the Product for its own use during the Warranty Period (“End User”). In all other
situations, this Limited Warranty is granted only to the first purchaser of the Product (“Immediate
Purchaser”) from SSLLC. No primary or remote purchaser or owner of the Product who is not a Warranty
Holder may claim any benefit under this Limited Warranty, or any remedial promise included in this Limited

Summary & Information
Important
The information contained herein is general in nature and not intended for specific application purposes. It

specifications shown herein or to make improvements at any time without notice or obligations. Should a
conflict arise between the general information contained in this publication and the contents of drawings or
supplementary material, or both, the latter shall take precedence.
CSH/CSH-B/CSH2/CSH2-B
The CSH/CSH-B and the CSH2/CSH2-B are similar products with the only difference being the
interrupting ratings of the device. This installation and instruction manual is written using the CSH-B as the
focus. The guidelines provided should also be utilized when installing the CSH2-B. This manual can also
be used as a guide for the CSH and CSH2 products which are similar but do not have the integral
disconnect.
Summary
These instructions do not purport to cover all details or variations in equipment, or provide for every
possible contingency to be met in connection with installation, operation, or maintenance. Should
information be desired or should particular problems arise which are not covered sufficiently for the
purchaser’s purposes, the matter should be referred to the local Southern States Representative.
The contents of this instruction manual should not become part of or modify any prior or existing
agreement, commitment or relationship. The sales contract contains the entire obligation of Southern
States. The Warranty contained in the contract between the parties is the sole warranty of Southern
States. Any statements contained herein do not create new warranties or modify the existing warranty.

Summary & Information
Introduction
The Southern States CSH-B horizontal circuit switcher is an outdoor, high voltage interrupting device equipped
with an in-series integral disconnect switch. Operation of the Southern States CSH-B is controlled by a motor
operator or by a manual worm gear operator. The Southern States CSH-B is designed and certified to switch
and protect transformers. The horizontal circuit switcher is also available without the integral disconnect
(CSH). For more information on this and other applications and ratings, contact the nearest Southern States
Representative.
A standard package consists of:
•3 phase SF6 gas CSH-B and support frame
•Support columns designed to customer specifications
•Accessory Box with SF6 gas fill kit
Additional information about the application and ratings of the CSH/CSH-B can be found in the latest updates
of Product Bulletins PB-803-40 and PB-803-20. For specific ratings for your device, refer to the product
nameplate and job specific drawings.
The instructions contained within this manual are necessary for the safe installation, maintenance, and
operation of the CSH-B. A qualified person, familiar with this type of equipment, should carefully read and
follow the instructions.
These instructions are intended to provide a general guideline for the installation, adjustment, and
Maintenance of the CSH-B. It is not possible to cover all details, equipment variations, and potential
conditions. Contact Southern States, LLC in the event conditions associated with a specific application are not
sufficiently addressed.
Distinctive signal words are used to indicate the degree of hazard that may be encountered by the user.
Identification of the signal words and their definition follow:
Indicates a possible material damage or can be used to highlight specific instructions
or notes.
Indicates an imminently hazardous situation, which, if not avoided, will result in death
or serious injury.
Indicates a potentially hazardous situation, which, if not avoided, could result in death
or serious injury.
Indicates a potentially hazardous situation, which, if not avoided, may result in minor
or moderate injury. It may also be used to alert against unsafe practices.

Product Description
Overview
The Type CSH is similar to the Type CSH-B. The CSH units do not have an integral disconnect blade. Line
termination is on the driver end. Two, rather than three insulator columns are used to support and operate the
interrupter. When referring to the Type CSH, omit sections of this manual relating to operation and adjustment
of the disconnect blade and hinge.

Product Description
Interrupter
The interrupter is an SF6 puffer design. The contact structure is robust and designed for many switching
operations. The CSH-B also utilizes a rupture disk that is designed to vent the gas in the event of an
overpressure condition inside the interrupter.
Figure 4: Interrupter
Appendix A-1 to RFP / Page 15 of 90 pages.

Page 6 of 78
Product Description
Interrupter trips with contacts “A” and “B” in the closed position. Contacts “A” and “B” remain in contact as “B”
travels over “A” and compresses the gas. Gas is ready to flow when contact part.
Contacts part – arcing begins – gas flows to extinguish the arc.
Gas divides the arc. Interruption complete.

Product Description
Operating Mechanism
A typical three-pole arrangement of the CSH-B is shown in Figure 6: Operating Mechanism. The three single
pole units are mechanically connected to operate simultaneously from a single operator, similar to group
operation of a disconnect switch.
The center insulator of each pole unit acts not only as a support but also as a torsion drive for the operation of
the disconnect switch and the interrupter. This center insulator is bolted to the shunt trip mechanism which, in
turn, is bolted to the lever and bearing assembly.
The interphase operating pipes connect the outside poles to the center pole. The center pole is driven by
means of a group control pipe, outboard bearing, vertical control pipe, and the operator. Operator rotation of
about 186 degrees provides an over toggle action at the full open and full close positions of the outboard
bearing.

Driver
The driver mechanism located at the top of the rotating insulator column contains the main closing springs,
shunt trip charging bolt, trip latch, and lever system that controls interrupter opening and closing. The main
operating shaft of the driver also operates the hinge mechanism of the disconnect switch.
Driver rotational positions are indicated by a green band and a red band shown in Figure 9: Driver. These do
not indicate interrupter position but are for adjustment purposes described later. A large window on the side of
the driver contains a semaphore that indicates interrupter contact position.
