FAQs

Installation requires dedicated attention to the drawout mounting framework and connecting the breaker to the cabinet’s bus and interface points. Ensure alignment with the vertical rack guides, secure motorized racking connections, and follow Eaton’s installation manuals for sequence, torque values, and safety clearances. Confirm enclosure suitability for 44.1 in width and 16.8 in height, and verify supply conditioning per local codes.
This MPSC6A4MEAXXSW ships without a trip unit. For enhanced protection, plan to integrate a Magnum PXR trip unit or compatible Magnum protection module selected to match application requirements. Verify compatibility with your existing protection strategy and ensure proper configuration to achieve intended overcurrent and short-circuit protection levels.
Yes. The unit is rated for 100 kA interrupt capability, making it suitable for high fault current environments common in large switchgear and MCC applications. When selecting this breaker, ensure the surrounding protection architecture and upstream devices are coordinated for reliable selective tripping and minimal arc energy exposure.
The product carries CE marking and NEMA compliance, with ANSI, KEMA, Lloyd's Register, UL Listed, CSA, DNV GL, and ABS certifications noted in its specification. This broad certification portfolio supports global deployments, simplifies regulatory approvals, and helps meet industry standards for safety, reliability, and performance.
The drawout design with motorized racking minimizes maintenance time and exposure to hazardous conditions, reducing downtime costs. A no-trip-unit baseline lowers upfront procurement costs, while modular protection options (via Magnum PXR) enable scalable protection. Overall, engineers can expect lower lifecycle maintenance costs and improved plant uptime through faster service and safer operation.
