EntelliGuard R Retrofill
Retrofill existing metal frame breaker cubicles with an EntelliGuard* G breaker
EntelliGuard R Retrofill helps make the most of your existing equipment.
Aging switchgear can often be a major cause of concern. Add to that the normal wear and tear on low-voltage circuit breakers to create a situation that may lead to a loss of system protection and reliability.
EntelliGuard R Retrofill provides a streamlined solution to update your legacy circuit breakers with a new EntelliGuard G Breaker, to give your existing switchgear a new lease on life. In addition to providing a host of new features, the EntelliGuard R Retrofill solution offers the option to include the EntelliGuard TU Trip Unit for both arc flash protection and selectivity at the same time. The EntelliGuard R offers a means to increase reliability and enhance the protection of your existing electrical system.
The EntelliGuard R Retrofill can provide savings right from the start because it makes the most of your existing equipment. Since it is 100% interchangeable with GE breakers, it:
- requires little to no cubicle modifications, minimizing shut down time during replacement;
- interfaces with the original cubicle secondary disconnects, position switches and neutral disconnects;
- is compatible with shutters in existing breaker cubicles;
- AK Retrofills utilize the EntelliGuard G lifting bar;
- makes the secondary disconnect wiring connection with no modifications to your switchgear;
- is available for GE and OEM built equipment.
