Selling Policy 25-000 - Distribution and Control Products and Services
Feature: High amperage and voltage ratings (2000A, 480V) enable protection of large feeders with minimal voltage drop. Business Impact: Reduces unplanned outages and supports reliable motor and feeder protection in critical processes. Application: Main distribution panels and motor feeders in heavy industrial environments. Feature: Single-phase voltage relay with capacitor trip device (SPVR) provides a precise, fast trip before fault escalation. Business Impact: Shortens fault clearance time, lowers arc-flash exposure, and improves system reliability. Application: Switchgear assemblies requiring capacitive trip logic for safe startup/shutdown. Feature: Bottom feed and bottom fuse configuration simplifies wiring and replacement. Business Impact: Reduces installation time, cabinet space, and maintenance labor. Application: New installations and retrofits in compact control rooms or large switchgear bays. Feature: Ground fault capability with control power transformer and optional ground fault relay. Business Impact: Enhances protection against ground faults, improving safety and compliance in critical loads. Application: Power distribution to sensitive equipment and critical process lines. Feature: NEMA ratings (1, 3R, 4, 12) and UL Listed certification ensure enclosure adaptability and compliance. Business Impact: Supports versatile installation in harsh environments, reducing lifecycle risk. Application: Outdoor and damp environments, harsh factories, and utility-scale panels. Feature: Comprehensive Eaton documentation and warranty (one year from installation or 18 months from shipment). Business Impact: Simplifies vendor support, improves total cost of ownership, and coordinates spare part planning. Application: Engineer-led procurement and after-sales planning for industrial installations.
