AKR Circuit Breaker Modernization Solutions
Many facilities still rely on legacy GE AK and AKR low-voltage power circuit breakers. In many cases, the switchgear lineup is still serviceable, but the breakers, trip units, and protection technology are outdated, difficult to support, or no longer aligned with current maintenance and safety requirements.
Bay Power helps facilities modernize aging AK and AKR breaker systems through practical upgrade paths, including EntelliGuard TU trip unit upgrades, ABB SACE Emax 2 retrofill replacements, breaker testing, repair, and phased modernization planning.
These solutions are designed for facilities that need to improve reliability, protection, and serviceability without the cost, downtime, and disruption of a full switchgear replacement.
Modernization Options for GE AK and AKR Breakers
EntelliGuard TU Trip Unit Upgrades
For mechanically sound breakers, an EntelliGuard TU trip unit upgrade may provide a practical way to extend service life while improving protection and maintenance capabilities. These upgrades can help modernize older trip systems while keeping the existing breaker and switchgear structure in place.
- Modern solid-state trip unit protection
- Maintenance mode and arc flash reduction capabilities
- Improved metering and system visibility
- Better supportability compared to older trip systems
- A modernization path without replacing the full switchgear lineup

ABB SACE Emax 2 Retrofill Replacements
For facilities that need a replacement breaker rather than a trip unit upgrade, ABB SACE Emax 2 retrofill solutions provide a modernization path for legacy GE AK, AKR, and WavePro power circuit breakers.
Emax 2 retrofill solutions can help reduce downtime by modernizing the breaker compartment without requiring a complete switchgear lineup replacement.
- Replacement path for obsolete AK and AKR breakers
- Reduced switchgear modification compared to full replacement
- Modern breaker platform with improved supportability
- Phased modernization across multiple breakers
- Less disruption than a complete lineup replacement

Built for Critical Facilities and Phased Shutdown Planning
AKR breaker modernization is especially important in facilities where downtime is difficult, expensive, or operationally unacceptable.
- Data centers
- Industrial plants
- Hospitals and healthcare facilities
- Commercial buildings
- Utility and infrastructure sites
- Manufacturing facilities
- Campuses and multi-building facilities
For data centers and other critical facilities, the goal is often not to replace everything at once. The better strategy may be a phased breaker modernization plan that works around shutdown windows, load priorities, and long-term infrastructure planning.
Bay Power can help evaluate breaker condition, identify upgrade paths, and support phased modernization projects that reduce risk without requiring a full switchgear replacement.
When to Consider an AKR Breaker Upgrade
- Replacement AK or AKR breakers are becoming harder to source
- Existing trip units are outdated or limited
- Arc flash reduction is a priority
- Breakers require repeated repair or calibration
- Maintenance teams need better metering or protection features
- The facility cannot support a full switchgear replacement
- You need a phased upgrade strategy across multiple breakers
