Retrofit Circuit Breaker Extends Switchgear Life

Hawker Siddeley Switchgear Ltd has unveiled its new SWR 12 retrofit Circuit Breaker, which will breathe new life into its existing range of oil and gas insulated switchgear. The South Wales Retrofit (SWR) 12 Circuit Breaker, designed to dramatically increase the life expectancy of the HG12 gas circuit breaker and the South Wales Switchgear ‘C’ and ‘D’ range of oil circuit breakers, boasts the latest in switchgear design technology, thanks to HSS’s awardwinning magnetic actuator.

The SWR 12 Circuit Breaker will extend the life of customers installed equipment while providing the opportunity to add greater functionality to the existing system. The SWR 12 Circuit Breaker can be fitted into existing switchboards without the need for panel modification or civil works. Its use of HSS’ patented ‘Fit and Forget’ magnetic actuator technology also means that it requires virtually no maintenance, which saves on costs.

As an air-insulated circuit breaker, the SWR 12 Circuit Breaker also removes the need for oil, or the SF6 ‘greenhouse’ gas, making it a greener and safer retrofit solution.

The SWR 12 is an OEM designed retrofit circuit breaker for both the South Wales Switchgear ‘C’ and ‘D’ range oil circuit breakers and the HG12 gas circuit breaker, to IEC 62271 – 100.
