Selling Policy 25-000 - Distribution and Control Products and Services
Integrated secondary breaker and 400A socket with a 1200A bus reduces panel count and wiring, delivering faster field installation and lower labor costs. In practice, you gain tighter protection coordination for downstream feeders and easier equipment upgrades over time. Three-phase 208Y/120V service with UL listing and NY approval ensures regulatory compliance and compatibility with standard commercial distributions. This combination minimizes rework and accelerates project timelines in multi-tenant buildings, retail centers, and light industrial sites. Seven-jaw, ringless design minimizes footprint while simplifying mounting and service access, improving reliability in tight electrical rooms. Lever bypass and factory A-B phase balance support uninterrupted service and balanced loads, enhancing uptime and energy efficiency for critical facilities. The unit’s compact dimensions—25 in L, 18 in W, 9 in H—and 98 lb weight facilitate transport, installation, and retrofit in constrained spaces. Built for durability, it aligns with Eaton warranty and service standards, delivering long-term reliability and predictable lifecycle costs.

FAQs
The 37MM140R12NY is a 25 in L x 18 in W x 9 in H meter stack designed for three-phase commercial distributions with a 208Y/120V service. It includes a K-frame secondary breaker and a seven-jaw ringless design, compatible with standard Eaton distribution panels and NY-approved installation practices. Ensure the service disconnect and bus are rated to 1200 A and that mounting clearances meet local codes for NY facilities.
Key specs include a 400A amperage rating, 1200A bus rating, and three-phase 208Y/120V service. The unit features seven jaws for robust conductor connections and a ringless design to maximize space efficiency. These specifications enable coordinated protection, reliable fault isolation, and scalable load capacity for mid-size commercial installations.
Yes. The 37MM140R12NY is NY-approved and UL Listed, making it suitable for NY commercial buildings and light industrial applications. Its 400A rating with a 1200A bus supports typical mid-range data centers or multi-tenant facilities, while the lever bypass and phase balance features aid service continuity and load management in demanding environments.
The meter stack carries UL Listed certification and NY approval, reflecting compliance with required safety and electrical standards. Warranty terms follow Eaton Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first, providing coverage for manufacturing defects and early service considerations.
Maintenance is typically reduced due to integrated components and fewer field connections. The built-in secondary breaker, lever bypass, and A-B phase balance simplify routine checks and fault isolation, lowering maintenance labor. The compact, sturdy design and NY-compliant features support faster project completion, predictable lifecycle costs, and enhanced uptime, contributing to a favorable total cost of ownership in mid-to-large commercial deployments.
