Eaton Specification Sheet - 35SS220RBC
Three-phase metering with 120/240V capability is designed to deliver accurate utility measurement while simplifying wiring and panel integration, reducing commissioning time and potential errors in complex power distributions. The five-jaw enclosure, two sockets, and socket amperage of 225A support flexible load distribution and future expansion, enabling straightforward upgrades without replacing the entire stack. The aluminum bus, rated at 1200A, provides robust fault tolerance and long-term reliability in demanding electrical environments, translating to lower maintenance costs and improved system uptime. Indoor/outdoor enclosure with NEMA 3R protection ensures weather resistance and safe outdoor installation, reducing site-specific enclosure requirements and accelerating project timelines. A built-in bypass test capability allows maintenance and testing to occur without full system shutdown, minimizing downtime during routine servicing and metering validation. UL Listed and EUSERC Approved certifications streamline utility approvals and inspections, helping projects pass regulatory checks on first submission and reducing risk of rework. Coupled with top, bottom, or back exit options, the stack supports flexible mounting in existing or new electrical rooms, ensuring compatibility with varied architectural and retrofit constraints across commercial facilities.

FAQs
The 35SS220RBC is designed for indoor/outdoor use with flexible exit options on the top, bottom, or back, enabling integration into a range of panel layouts. It supports three-phase in and single-phase out at 120/240V, with a 200A socket rating and five-jaw bus, allowing straightforward retrofit into existing metering enclosures or new installations. This flexibility minimizes wiring changes and helps meet space constraints in retrofit projects.
Interrupt rating for the 35SS220RBC depends on the selected main circuit breaker. The unit provides a 200A socket amperage and a 1200A bus rating, which means the system is designed to accommodate a main breaker sized to meet the application’s fault current requirements. This aligned approach helps ensure proper coordination, protection, and regulatory compliance without oversizing components.
Yes. The 35SS220RBC supports 120/240V single-phase three-wire configurations and 208Y/120V networks, as noted in catalog notes. Its three-phase in and single-phase out configuration, combined with a 1200A bus and aluminum construction, makes it suitable for commercial metering and distribution in facilities requiring accurate energy measurement and flexible network metering.
The meter stack is UL Listed and EUSERC Approved, indicating compliance with safety and utility metering standards. The enclosure is rated for indoor/outdoor use with rainproof considerations (NEMA 3R noted in application guidance), supporting outdoor installations. These certifications simplify inspections and help ensure adherence to utility and building code requirements during project review.
The built-in test bypass enables metering and circuit testing without interrupting power to connected loads, reducing downtime during preventive maintenance or metering validation. Combined with a durable aluminum bus and robust enclosure, this feature lowers maintenance costs and extends service intervals, contributing to a quicker return on investment through reduced outage time and smoother regulatory testing.
