FAQs
MPS8604WEAXX2F uses a drawout vertical mounting and a four-pole Magnum PXR frame, making it compatible with standard low-voltage switchgear housings and bus configurations. Ensure the installation footprint matches the double-standard frame dimensions, confirm upstream and downstream coordination, and verify the Power Xpert Release trip unit is configured for your protection scheme. The unit supports straightforward retrofits and maintenance, reducing commissioning time.
Key specs include a rated uninterrupted current (Iu) of 6000 A and an interrupt rating of 85 kAIC. It is a four-pole, drawout device with a Magnum PXR trip unit, designed for high fault currents. Dimensions are 16.3 in (L) x 16.8 in (H) x 44.1 in (W) and weight around 319 lb, enabling robust protection in large switchgear assemblies.
Yes. The 6000 A Iu and 85 kAIC rating support demanding fault-current environments typical of data centers, continuous industrial processes, and heavy manufacturing lines. The drawout PXR trip unit provides adjustable protection, while Power Xpert integration enables monitoring and coordination with upstream protection, improving uptime, reliability, and safety in critical facilities.
The unit carries UL Listed, CSA Certified, and CE Marked credentials, along with NEMA compliance and additional industry approvals. These marks indicate conformance to safety and performance standards across major regions, simplifying procurement, assuring regulatory compliance, and facilitating smoother project sign-off in multinational deployments.
Power Xpert Protection Manager compatibility provides remote monitoring, event logging, and trip history, enabling predictive maintenance and faster fault diagnosis. This reduces unscheduled downtime, lowers spare-part stock requirements, and shortens maintenance windows, delivering tangible ROI through increased productivity and lower total cost of ownership over the breaker’s life cycle.
