Overview
SES provides onsite or offsite Circuit Breaker Retrofits for a variety of customers including Steel Mills, Government Research Facilities, Power Plants, and many more. We offer several levels of service including Life Extension Maintenance options.
Why Retrofit a Circuit Breaker?
There are several reasons why a Circuit Breaker Retrofit may be necessary. The most common reason is the existing electro-mechanical, solid state, or early model microprocessor trip unit does not function accurately. If so, the Circuit Breaker will not trip as designed. Another reason is the cost to Retrofit versus the cost to replace. Replacing an entire switchboard is very expensive when accounting for the bill of materials, engineering, construction, and commissioning. SES customer's save millions of dollars by making the decision to retrofit entire substations rather than replace the entire substation's circuit breakers.
Circuit Breaker Retrofit Explained
Prior to the eventual failure of a Circuit Breaker's components, installing modern and precise parts increases the accuracy and overall performance of the Circuit Breaker.
