FAQs

Install the unit in a compatible panel using its drawout vertical mounting and four-pole configuration. Verify the catalog number MPS84N4WEAXX2Q, connect busbars per the panel design, and set the PXR25 LSIAM trip unit prior to energization. Ensure clearance for maintenance, torque requirements per the manual, and proper safety procedures for safe operation.
This breaker delivers an 85 kA interrupting capacity within a 4000 A frame. The high short-circuit rating enables selective coordination with downstream devices, minimizing nuisance trips and limiting arc energy. In practice, coordinate with nearby protective devices to maintain reliable protection across motor feeders and critical loads.
Yes. The four-pole Magnum breaker with Power Xpert Release trip unit is designed for motor protection in MCCs. It supports accurate overcurrent protection, coordination with variable frequency drives, and simplified motor control center integration. Use the PXR25 settings to tailor protection to motor startup currents and operating profiles for reduced wear and downtime.
The MPS84N4WEAXX2Q carries UL Listed, CSA Certified, ANSI/CE markings, and NEMA compliance, along with KEMA, Lloyd's Register, DNV GL, and ABS certifications. These attest to safety, reliability, and regulatory compliance across multiple regions, streamlining supplier qualification, QA audits, and global installations.
Power Xpert Release trip units simplify tuning and diagnostics, enabling faster commissioning and targeted protection settings. This reduces unplanned downtime, extends equipment life, and lowers lifecycle costs. Access to technical docs, time/current curves, and manuals further enhances predictive maintenance and operator confidence in complex automation environments.
