Four-pole design with 100 kA interrupting capacity delivers robust feeder protection, reducing the risk of outages and improving plant availability in demanding industrial environments. In practical terms, this means fewer unplanned trips and more predictable operation for critical loads such as motors and conveyors. The drawout vertical mounting with motorized racking simplifies installation and maintenance, enabling safer, quicker maintenance windows and reduced arc flash exposure during breaker changes. The PXR20 LSIAM trip unit provides advanced protection and diagnostics, supporting precise coordination and easier configuration via Power Xpert tools to meet selective coordination requirements in complex switchgear. With a 5000 A breaking capacity (NNAABBCC) and compatibility with Power Xpert Protection Manager, this breaker integrates into modern, data-driven maintenance programs. Industry-standard certifications and wide compatibility support regulatory compliance and smoother retrofits across facilities.

FAQs

Install the MPSC5N4MEAXX2H in compatible four-pole, drawout vertical switchgear using the factory motorized racking system. Follow the manual mn013016en for wiring, alignment, and safe engagement of the PXR20 LSIAM trip unit. Ensure proper clearances, verify mechanical interlocks, and perform functional testing with the Power Xpert Protection Manager before live commissioning.
Key specs include four poles, 100 kA interrupting rating, and 5000 A short-circuit current rating (NNAABBCC). Catalog number MPSC5N4MEAXX2H, weight around 319 lb, dimensions 16.3 in (depth) Ă— 16.8 in (height) Ă— 44.1 in (width). The unit uses a Power Xpert Release (PXR) trip system with LSIAM, suitable for selective coordination and diagnostics.
Yes. The four-pole, drawout design with motorized racking is ideal for motor control centers, enabling quick breaker changes and safer maintenance. The PXR20 LSIAM trip unit supports selective coordination, reducing nuisance trips while maintaining protection for high-inertia motors. Its compatibility with Power Xpert Protection Manager aids in monitoring and coordination across MCC compartments.
The MPSC5N4MEAXX2H carries UL Listed, CE Marked, and CSA Certified status, with additional approvals such as ANSI, Lloyd's Register, KEMA, ABS, and SABA where applicable. It also aligns with NEMA Compliant and CCC Marked requirements, providing broad regulatory assurance for global installations and retrofit projects.
Power Xpert Release enables precise protection settings, enhanced coordination, and richer diagnostics. This reduces unplanned downtime, streamlines maintenance planning, and shortens inspection windows. Over time, the ability to monitor and adjust protection remotely supports predictive maintenance programs, delivering lower operating costs and improved asset availability.
