FAQs

Yes. The MPSC123VEAXX2A uses a standard Magnum frame with fixed vertical mounting, designed to drop into compatible panels without extensive rewiring. Its three-pole construction aligns with common busbar configurations, and the unit ships with mounting hardware suitable for retrofit projects. Always confirm busbar pitch and panel clearance during scope definition to ensure a smooth upgrade.
The breaker supports a 1200 A continuous rating and 100 kA interrupting capacity across a three-pole configuration with a PXR20 LSI trip unit. This combination enables robust fault handling, selective coordination, and arc-flash reduction in demanding lines. It is well-suited for high-current motors and distribution panels where uptime and safety are priorities.
This model is ideal for main protection in manufacturing lines, stamping presses, conveyors, and process equipment where large fault currents can occur. Its compatibility with Power Xpert protection workflows makes it a strong fit for integrated control architectures and modernized panels needing reliable, code-compliant protection.
Consider UL Listed and CE Marked as core cross-border requirements. The product also has ANSI/KEMA certifications and is listed by additional bodies such as CSA, Lloyd’s Register, ABS, and DNV GL. These certifications support global deployment, reduce site-specific approval time, and help ensure project acceptance in regulated industries.
Plan for lifecycle support with available renewal parts and accessories and leverage Power Xpert Protection Manager for proactive monitoring. The device’s durability, modular trip-unit options, and global certification profile typically translate to lower downtime, fewer spare-part variations, and faster fault diagnosis, delivering a favorable return on investment over the equipment lifecycle.
