Life Extension/Retrofill

Circuit Breaker Sales' life-extension programs also offer retrofill options. CBS' retrofill service strips out the old obsolete or underrated equipment from one of your existing enclosures or cans, or a similar model unit from our inventory, and installs a complete new assembly draw-out structure with a new breaker or contactor, or an all-new assembly, within the existing enclosure. This saves our customers the cost of replacing entire line ups while gaining the peace of mind that comes from having the latest electrical distribution and protection equipment.

Circuit Breaker Retrofill

Examples of CBS's retrofill services include:

  • Upgrading low-voltage circuit breakers with new cradle. breakers, doors, and interlocks.
  • Replacing obsolete low-voltage power circuit breakers in existing line ups with modern insulated case circuit breakers that have higher interrupting capacities and modern solid-state electronics.
  • Updating medium-voltage motor controls with GE Multilin motor relays, for example.
  • New buckets for your low-voltage motor control centers.
  • New vacuum interrupters to replace older large, low-voltage air breaker motor controls, or medium voltage overcurrent protection devices.
  • Changing out oil, or air-cooled dry-type transformers with more efficient and robust cast-resin power transformers.
  • ....And much, much more. Contact us to see if we have a retrofit solution for your needs
