Retrofit Circuit Breakers
www.systemprotection.in
Why Retrofit? • Fault level upgrades - where the fixed portion needs to be compatible with a proposed enhanced rating
www.systemprotection.in
• Remote control of switchgear – many originally manufactured ocb’s have manually operated mechanisms that cannot be converted to electrical release or motor charged mechanisms www.systemprotection.in
• Troublesome individual breakers on a multipanel switchboard where there are no technical or economical reasons to change the switchboard
www.systemprotection.in
• Desire to upgrade the moving portion but cannot practically consider installing new switchgear (i.e. process industry)
www.systemprotection.in
• Less maintenance and asset management costs (no oil, frequency of maintenance reduced, post fault maintenance reduced)
www.systemprotection.in
• Loss of expertise on particular ranges of circuit breaker
www.systemprotection.in
• Lack of availability of spares for oil circuit breakers

Change of duty – increased frequency of switching
www.systemprotection.in
Increase in circuit rating from 400-630A (or upgrade from 400-1250A if other internal components changed)
