Circuit Breaker Retrofill Solutions

Features a Masterpact cradle and circuit breaker, along with a new racking mechanism and primary and secondary connections in each switchgear cell. Existing cells are modified to accept the new cradle and circuit breaker, including a custom-engineered connection between the cradle and the switchgear line and load side bus. Custom designs are available for any manufacturer’s low voltage switchgear.

This solution upgrades switchgear by installing a new medium-voltage circuit breaker and cell into an existing line-up. Necessary modifications – including an all-new racking mechanism, primary and secondary disconnects, and customized connections – are made to the existing cell. Available designs include: 

• Air-magnetic to vacuum or SF6
• Air-blast to vacuum or SF6
• OCB switchgear to vacuum or SF6 switchgear
• Convert stationary circuit breaker to draw-out, or obsolete air circuit breaker to vacuum or SF6
