FAQs

The MPS84N4MEAXX2C uses a drawout vertical design with motorized racking, enabling quick insertion and removal in existing panel buses. It supports the Magnum PXR trip unit family and a double-standard frame, ensuring compatibility with many standard LV switchgear configurations. For retrofit projects, verify mounting rails, clearance, and access to the racking mechanism to minimize downtime.
Key specs include 4000 A Iu rated uninterrupted current and an 85 kAIC interrupt rating, four poles, and a PXR20 LSIG trip unit. These deliver high-current capacity with fast fault clearance, enabling precise coordination and reducing the risk of cascading trips in high-load environments such as motors and conveyors.
Yes. With 4000 A Iu and 85 kAIC, it accommodates large motor loads and heavy electrical demand typical in manufacturing plants, data centers, and process industries. The four-pole construction and LSIG trip unit provide reliable protection, while motorized racking supports efficient maintenance without extensive panel downtime.
The MPS84N4MEAXX2C carries UL Listed, CSA Certified, and CE Marked status, with additional accreditations such as Lloyd's Register and CCC where applicable. These certifications support regulatory compliance across global markets and ease procurement for multinational projects demanding cross-scheme approval.
The combination of a motorized racking system and easy drawout design reduces maintenance time and labor costs, while the high interrupt rating and precise LSIG protection minimize outage durations. This translates to lower downtime costs, longer asset life, and improved plant availability, delivering a favorable return on protection investment over the lifecycle.
