Eaton Specification Sheet - PXMP-MB-4B-A
Enclosed meter with a rugged NEMA 4X enclosure protects sensitive metering electronics from dust, moisture, and corrosive exposure, reducing field failures and maintenance costs. This protection translates into longer service life in outdoor or harsh indoor environments and provides operational continuity for critical processes. The 3-phase/4-wire main fuse disconnect integrated into the PXMP-MB-4B-A simplifies wiring, enhances safety, and speeds commissioning, delivering quicker time-to-value in new builds or panel upgrades. A no-display design reduces vandalism risk and panel clutter, while still enabling remote telemetry integration with SCADA or energy management systems for real-time monitoring and control. The power supply of 120/240 Vac offers flexible installation with common control voltages, minimizing adapters and conversions and supporting rapid retrofits. Certifications such as ANSI/IEEE C12.20 at 0.2% accuracy, ANSI/IEEE C62.41, IEC 687, and CE marking provide confidence for compliance, billing accuracy, and safety audits. With dimensions of 18 in length, 27 in width, and 33 in height and a 100 lb footprint, the unit fits predictable panel spaces and simplifies layout planning. PXMP as a meter type ensures compatibility with Eaton’s broader metering and protection portfolio, reducing spares variety and streamlining maintenance.
