Eaton Specification Sheet - 37MM240R124095
The 37MM240R124095 meter stack delivers a robust 400A rating with two sockets, enabling quick, compliant connections for essential feeders and downstream distribution. This feature translates to measurable business impact: safer, faster installation and reduced field wiring time, which lowers labor costs and accelerates time-to-power. In practice, electricians can rely on a ringless cover and lever bypass to streamline maintenance, minimize outage windows, and facilitate rapid isolation during troubleshooting in commercial facilities. The integrated K-frame secondary breaker and seven-jaws design support reliable fault protection and simple retrofits, improving uptime and asset protection for data centers, offices, or retail environments. With 208Y/120V operation and solid aluminum bus for high reliability, the unit supports scalable metering as facilities grow, reducing the need for costly enclosure replacements. Compatibility with Eaton metering products and standard low‑voltage distribution practices makes this stack an easy fit for existing electrical rooms and new builds alike. The enclosure’s dimensions—66.625 in long, 8.75 in high, and 19.375 in wide—offer predictable space planning and installation efficiency, while UL certification and a one‑year to eighteen‑month warranty framework provide purchasing confidence and long‑term support.
