Drawout vertical mounting and a four-pole configuration simplify integration into large switchboards, enabling safe, tool-assisted replacement with minimal panel disturbance. This design reduces commissioning time and boosts maintenance efficiency in high-density panels. High current rating of 1600 A and a 100 kA breaking capacity provide robust protection against severe short circuits, safeguarding feeders and motors while limiting fault damage and downtime. The unit ships as a no-trip-unit device, offering flexibility to install a Power Xpert Release trip unit (PXR) for advanced protection features, including selective coordination and zone-selective interlocking when required by the application. Certifications including UL Listed, CSA Certified, ANSI, CE Marked, and independent attestations (KEMA, Lloyd’s Register, ABS, DNV GL, SABA, CCC) simplify procurement and regulatory compliance across regions. The heavy-duty construction and 160 lb chassis support long service life and reliable performance under demanding industrial conditions, reducing maintenance cycles and improving overall equipment uptime. The package is compatible with Magnum PXR protection ecosystems, enabling future upgrades without replacing the base breaker, which translates to lower total cost of ownership in evolving control architectures. Application versatility spans panel boards, switchgear, and high-load industrial environments such as manufacturing lines and process industries.

FAQs

This four-pole, drawout vertical unit is designed for installation into standard low-voltage panels. Ensure proper alignment with mounting rails, confirm secure drawout engagement, and use compatible wiring and lugs. Note that this variant ships without a trip unit, so plan for installing a Power Xpert Release trip unit (PXR) if advanced protection, selective coordination, or interlocking is required. Refer to the Magna PXR manuals for installation guidance and weight considerations (approximately 160 lb).
The MPSC164WEAXXSW is a four-pole breaker rated at 1600 A with a 100 kA breaking capacity, suitable for high-current feeders and motor circuits. It is designed for drawout vertical mounting and ships without a trip unit, allowing future upgrade to a PXR protection scheme.
Yes. While shipped without a trip unit, the breaker is compatible with Power Xpert Release trip units for Magnum PXR, enabling selective coordination. For zone selective interlocking, consult Eaton application papers and the Zone Selective Interlocking guidance to ensure proper system integration.
The MPSC164WEAXXSW carries UL Listed and CSA Certified marks, along with CE marking and additional third-party certifications (KEMA, Lloyd’s Register, ABS, DNV GL, SABA, CCC, etc.). These certifications support regulatory compliance, global procurement, and safe operation in multi-region facilities, simplifying panel approvals and reducing supplier risk.
The four-pole drawout design supports safer, faster maintenance and replacement, reducing downtime. Compatibility with PXR trip units allows future protection upgrades without changing the base breaker, lowering total cost of ownership. High fault-current protection (1600 A, 100 kA) helps safeguard downstream equipment, potentially reducing repair costs and improving system uptime.
