The drawout vertical mounting with motorized racking simplifies maintenance by enabling remote operation and safe, swift rack-and-unrack cycles, reducing downtime in panel and MCC environments. This feature translates to measurable time savings during reconfiguration or servicing and improves maintenance crew safety during routine inspections. The 1600 A frame with a 100 kA interrupt rating supports large loads and high fault-current environments, delivering reliable protection for motor feeders and critical plant equipment while easing future capacity expansions. As a no-trip-unit device, it provides maximum flexibility to pair with Power Xpert Release trip units or existing protection strategies, allowing designers to tailor coordination and meet site-specific protection requirements. Global certifications — including CE, NEMA, UL, CSA, and ANSI — minimize procurement risk across multinational projects. Its precise dimensions and weight (14.6 in depth, 16.8 in height, 16.2 in width, 118 lb) enable compatibility with standard enclosures and retrofit installations, enhancing installation efficiency and reducing cabinet modifications.

FAQs

The MPSC163MEAXXSW uses a drawout vertical design and motorized racking, enabling safer and faster maintenance in standard enclosures. When retrofitting, verify enclosure clearance, mounting rails, and access to racking mechanisms, and ensure the panel supports a compatible drawout breaker footprint. The absence of a trip unit means you must select a suitable protection strategy or add a compatible Power Xpert Release unit.
This model is a 1600 A frame unit with a 100 kA interrupt rating, three-pole configuration, and a drawout vertical mounting. These specifications enable reliable interruption of high fault currents in large industrial feeders and motor circuits, while maintaining compatibility with heavy-duty distribution systems.
The MPSC163MEAXXSW ships without a trip unit, but it is designed to be paired with compatible Power Xpert Release trip units for customized protection and coordination. When paired, it can be monitored and managed via Power Xpert Protection Manager, aligning with modern digital protection strategies.
The unit carries UL Listed and CSA Certified approvals, along with ANSI and Lloyd's Register certifications. It is CE marked and NEMA compliant, with additional CCC marking. These certifications support global procurement and compliance across multinational projects.
Motorized racking reduces manual handling, speeds up supplier-to-service transitions, and minimizes arc-flash exposure during rack/unrack operations. Coupled with a robust 1600 A/100 kA rating and a flexible trip-unit strategy, it yields faster commissioning, safer maintenance, and lower total cost of ownership for critical electrical distribution networks.
