Learn About Our Vertical Circuit Switchers

Circuit Switchers – Vertical (CSV, CSV-CB-DB)

Southern States’ CSV (“candlestick”) circuit switcher, with vertical interrupters, is designed specifically for transformer protection and switching applications where substation space is limited. Unlike traditional general purpose circuit breakers, these devices account for the fast rate-of-rise transient recovery voltage (TRVs) during the interruption of a transformer limited fault.

Additionally, the CSV can be integrated with a Southern States disconnect switch. Most commonly, these designs include an integral double sidebreak “vee” switch (CSV-DB) or an integral center break “vee” switch (CSV-CB). Both can be specified for manual or motor operation.

Compared to dead tank circuit breakers, circuit switchers have a significantly smaller footprint and utilize significantly less SF6
Simple, easy erection minimizes field installation time required.
Structure baseplate can have its hole locations and hole sizes varied when required to fit existing foundation locations and anchor bolt sizes.
Gas density switch with low pressure alarm and low pressure lockout contacts allow remote gas monitoring.
Local visual indication of gas system by an SF6 pressure gauge.
Ships with minimal gas pressure for safety during transportation and in handling during installation.
Adaptable to a wide variety of installation height requirements and foundation requirements.
4 hole NEMA terminal pads are readily reversible to fit specific installation requirements.
Each unit is completely assembled and tested at the factory with only the disassembly required to meet shipment restrictions being performed
