Selling Policy 25-000 - Distribution and Control Products and Services
Feature: High amperage rating and multi‑voltage compatibility. Business Impact: Enables large motor feeders and high‑fault‑current protection with a single device, reducing the need for multiple switches or adapters. Application: Three‑phase MCCs and central distribution panels where 2000A at 480V is required and 120V control power is available. The design simplifies procurement and spares planning while improving uptime. Feature: Three‑pole, 1NO‑1NC contact configuration with bottom feed. Business Impact: Tightens control of switching sequences and reduces wiring complexity in confined spaces. Application: Industrial switchgear where bottom‑fed, fusible protection is preferred for compact layouts and safer service access.Feature: Fusible protection with optional Ground Fault Relay and other catalog notes. Business Impact: Enhances protection coordination and fault discrimination, lowering the risk of cascading trips. Application: Panels requiring selective protection and compliance with protective relay schemes. Feature: NEMA 1, 3R, 4, 12 ratings and UL Listed certification. Business Impact: Supports regulatory compliance and durable operation in harsh environments, reducing warranty claims. Application: Outdoor or dirty environments and enclosed control rooms where rugged enclosure protection is essential.Feature: BFD with three normally on lights and charge‑before‑close mechanism. Business Impact: Improves situational awareness and safe operation during maintenance or test sequences. Application: Critical protective interlocks in motor control centers and process lines. Feature: Optional auxiliary contacts and provisions for Kirk and other protection options. Business Impact: Extends diagnostic capability and integration with centralized control systems. Application: Complex protection schemes requiring monitoring and interlocking across multiple devices.
