Retrofill / Retrofit

Retrofill & Retrofit existing ME07 metal frame breaker cubicles with an EntelliGuard R breaker


EntelliGuard R Retrofill & Retrofit helps make the most of your existing equipment.

In any electrical installation, aging equipment can often be a major cause of concern. Added to that the normal wear and tear on low-voltage circuit breakers that may lead to a loss of system protection and reliability.

Many times the existing switchgear is intact, but the breakers are worn out and spares are becoming obsolete.


GE with its vast experience and expertise in air circuit breaker technology offers both Retrofill & Retrofit solutions for the former AEG breaker ME00, 05, 06, 07 breakers installed in your plant with the proven EntelliGuard breakers line.


EntelliGuard R are Retrofills, that is "roll-in" replacements for aging legacy breakers. With this product users can upgrade and update existing switchgear by only swapping the moving portion of a ME07 with a brand new EntelliGuard breaker
leaving the existing cassette and cubicle virtually intact.
This convenient design ultimately minimizes both downtime and impact on the existing switchgear.


GE complements its Retrofill(1) range with Retrofits(2) where "roll-in" replacements may not be possible. A Retrofit in comparison to a Retrofill, may require cubicle and busbar modifications

(1) The existing trip free mechanism, switchboard doors and in some cases also the carriage position requires modification
(2) Retrofit solutions upon request from our after sales and services department

The EntelliGuard R breakers are supplied from the factory almost “Ready to Fit” into existing ME07 cassettes.
