SACE Emax 2 Retrofill Circuit Breaker

Advanced retrofill solutions with SACE® Emax 2 to replace legacy GE AK, AKR, and WavePro circuit breakers in legacy GE AKD-5, AKD-6, AKD-8, AKD-10 and OEM switchgear.

Designed to retrofill the existing low-voltage circuit breaker compartment with a streamlined solution that gives the switchgear a new lease on life. Emax 2 Retrofill replaces the existing legacy breaker with a modern breaker, that does not require cubicle bus or racking modifications. This means minimal downtime while making the change. Compatible with existing legacy GE AKD-5, 6, 8 10 - switchgear, the Emax 2 Retrofill Circuit Breaker has an interrupting rating equal to or greater than the legacy breaker. The Retrofill circuit breaker meets the standards and testing criteria of the latest version of ANSI, NEMA, and IEEE.

Benefits

Reduced project and labor costs

• Retains existing switchgear structure, conduits, cabling and footprint
• Secondary disconnect wiring connection works without modifications to your switchgear
• Innovative neutral CT adapter design allows you to use existing neutral CT in your switchgear
• Maintains UL listings without additional charges

Minimized downtime

• Minimal or no cubicle modifications means decreased change-out times
• Compatible with shutters racking mechanism in existing circuit breaker cubicles
• Interfaces with original cubicle secondary disconnects, position switches and neutral disconnects

Protection for people and equipment

• Exclusive Ekip Trip Unit technology uses zone selective interlocking (ZSI), Dual setting protection, reduced energy let-through (RELT), and helps reduce arc flash energy without sacrificing selectivity settings.
• Trip unit and all indicators are visible through the door; through-the-door and remote racking helps reduce exposure to arc flash or electrical shock.

Continuous operation

PREDICT feature in ABB Ability™ Energy and Asset Manager for Predictive Maintenance. Reduction of the total life cost of the switchgear and spare parts availability. Diagnosis and installation with Ekip Connect Software.

Sustainability

Help extend the life span of your electrical equipment by keeping it operational and efficient, without costly cubicle modifications. Help to reduce energy use and carbon emissions.
