Four-pole construction with drawout vertical mounting and motorized racking simplifies servicing and reduces downtime during maintenance or replacement in heavy-duty switchgear environments, boosting overall line availability and safety. The enhanced protection provided by the PXR20 LSIG trip unit yields precise, adjustable protection curves that improve coordination with downstream devices, lowering the probability of cascading trips in complex power networks. With a high fault-current rating of up to 85 kA and a 6000 A breaking capacity, this breaker maintains reliable operation in systems with elevated fault potential, minimizing catastrophic failures and associated costs. Its robust, fan-cooled design supports continuous operation in harsh plant conditions, preserving performance and reducing cooling-related energy use. The unit’s drawout mechanism and motorized racking enable quicker replacements and safer handling, while the compact form-factor and documented installation procedures reduce commissioning time and field errors. Compliance documentation and a comprehensive set of application notes further support regulatory adherence and lifecycle management, helping procurement justify total cost of ownership and long-term ROI.

FAQs
The MPS8604MEAXX2C uses a drawout vertical mounting with motorized racking, compatible with Magnum PXR frames and standard low-voltage distribution panels that support four-pole breakers. Ensure mounting footprint matches the device footprint (approx. 16.3 in L × 16.8 in H × 44.1 in W) and confirm service access for motorized racking. Follow Eaton’s installation guides for wiring diagrams and torque specs.
Key specifications include a four-pole construction, 6000 A interrupting capacity (NNABCABC) and an 85 kA short-circuit withstand rating. The unit uses a PXR20 LSIG trip system for selective protection, is fan-cooled, and supports motor protection scenarios. These features enable reliable performance in demanding industrial circuits while minimizing nuisance trips.
Yes. The four-pole Magnum breaker with PXR20 LSIG protection is designed for motor feeders and process line protection within low-voltage power distribution. Its motorized racking and drawout mounting streamline maintenance in MCCs, and the PXR trip unit helps coordinate protection with variable-speed drives and other upstream/downstream devices, reducing unplanned outages.
The device is CE Marked and UL Listed, with additional certifications including CCC Marked, NEMA Compliant, and SABA Listed. Other listed certifications (CSA, KEMA, ANSI, Lloyd's Register, ABS, DNV GL) may be applicable depending on region and model variants. Always verify the latest certification set on Eaton’s datasheet or certificates of compliance for your project.
Schedule periodic functional checks of the LSIG trip unit, inspect motorized racking mechanics, and verify cooling efficiency during routine maintenance. The unit’s protection precision reduces nuisance trips, lowers mean time to repair, and minimizes downtime costs. The documented specifications and easy-to-follow manuals also shorten onboarding for maintenance teams, supporting a favorable total cost of ownership.
