EntelliGuard® R Retrofill

Retrofill existing metal frame breaker cubicles with an EntelliGuard® G Breaker


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.
