Eaton 35SS320RAB Meter Stack 120/240V - UL Listed
Part Number: 35SS320RAB
Quick Summary
The Eaton 35SS320RAB meter stack is a rugged 200A commercial metering solution designed to power 120/240V installations in modern panels. Engineers often struggle with mounting flexibility, weather exposure, and bus-rating limits in high-load metering, and this stack addresses those challenges with configurable exit options and a durable aluminum enclosure. UL Listed and EUSERC Approved, with a NEMA 3R enclosure for indoor/outdoor service, this unit also supports 208Y/120V networks and offers a test bypass for safe maintenance. In practice, this combination improves installation speed, compliance confidence, and overall total cost of ownership for facilities teams and specifiers, while aligning with power management and distribution best practices.
