FAQs

Yes. The MPSC123MEAXX2H is designed with a drawout vertical mounting and motorized racking, simplifying replacement and service. Its standard frame supports retrofit into existing panels, reducing downtime during maintenance and enabling fast, safe seating and withdrawal in demanding industrial environments.
The breaker uses a Power Xpert Release PXR20 LSIAM trip unit, delivering advanced instantaneous protection and adjustable long-time and short-circuit protection. It enables selective coordination to minimize downstream disruption and reduces arc-flash risk by providing precise, reliable tripping under fault conditions.
The MPSC123MEAXX2H carries CE Marked, UL Listed, and CSA Certified markings, with additional CCC Marked and SABA Listed certifications noted in documentation. This broad certification portfolio supports compliance in Europe, North America, and other regions, facilitating procurement and cross-border installation.
Typical applications include data centers, manufacturing lines, process plants, and any heavy-load distribution feeders requiring high fault-current interruption. With 1200 A rating and 100 kA breaking capacity, it protects large feeders while enabling scalable protection strategies and integration with protection management software.
Motorized racking minimizes manual handling, reduces maintenance time, and lowers the risk of improper seating. This translates to shorter outage windows, faster turnarounds for replacements, and lower total cost of ownership through improved reliability and easier lifecycle management of critical power distribution equipment.
