Selling Policy 25-000 - Distribution and Control Products and Services
Feature: 4000 A amperage rating with a 1 NO-1 NC contact configuration. Business Impact: Enables direct interruption of large fault currents at the source, reducing downstream device ratings and easing protection coordination. Application: Ideal for main feeders in switchgear and high-load motor circuits where fast, reliable isolation is critical. An additional benefit is compatibility with 120 V control circuits and a 480 V system, enabling seamless integration with existing plant controls. Feature: Top feed fusible configuration with top-wiring access. Business Impact: Simplifies wiring, minimizes misconnection risk, and supports straightforward maintenance. Application: Suitable for compact control cabinets and outdoor enclosures where space and accessibility are concerns. Feature: Three-pole, three-wire arrangement. Business Impact: Delivers precise phase control and coordinated switching across three-phase systems, improving reliability and reducing arcing risk. Application: Used in heavy-duty industrial power distribution and control panels. Feature: NEMA rating support (NEMA 1, 3R, 4, 12). Business Impact: Extends installation options from clean indoor environments to outdoor and washdown areas, lowering enclosure requirements. Application: Flexible in harsh environments, from factories to outdoor equipment rooms. Feature: Electrical trip with charge-before-close mechanism. Business Impact: Safer energization sequences and arc-reduction during startup, lowering personnel risk and downtime. Application: Critical in safety-conscious motor start and process control applications. Feature: Optional accessories (Ground Fault Relay, Blown Fuse Detection, Auxiliary Contacts). Business Impact: Enables customized protection schemes to meet specific codes and diagnostics, reducing unplanned outages. Application: Compliance-driven installations that demand enhanced monitoring and control features.
