FAQ: LP33 Discontinuation

When did the ABB GE LP33 Series become discontinued?
The ABB GE Critical Power LP33 Series was officially designated as End-of-Life (EOL) in 2023. While some units may still be operational in the field, ABB GE has ceased manufacturing and full factory support for this UPS line. End-users are strongly encouraged to evaluate replacement options to ensure continuity and compliance with modern critical power standards.

What does “end-of-life” mean for parts & service?
“End-of-life” (EOL) means that ABB GE no longer manufactures, updates, or supports the LP33 UPS systems. This includes:

• Discontinued production of new units

• Limited or no availability of OEM replacement parts

• Cessation of firmware or software updates

• Reduced availability of certified technical support

While some third-party vendors may still offer limited service, support becomes more costly and less reliable over time. For mission-critical environments, transitioning to a current-generation UPS like the M90U is highly recommended.

Can existing LP33 units be upgraded or retrofitted?
In most cases, LP33 systems cannot be meaningfully upgraded due to outdated architecture and limited parts availability. Retrofitting may offer short-term fixes, but does not address long-term reliability, energy efficiency, or compliance requirements.
XPCC offers a range of modern, modular UPS solutions—like the M90U Series—that are specifically designed to replace LP33 systems with minimal disruption and improved performance.
