Selling Policy 25-000 - Distribution and Control Products and Services
Feature: Adjustable thermal and adjustable magnetic trip provide precise overcurrent protection tailored to each application. Business impact: improves selective coordination, reduces nuisance trips, and minimizes equipment wear by preventing unnecessary disconnections. Application: ideal for control panels in packaging lines, conveyors, and machine tools where fault currents vary with load, startup surges, and process changes. Feature: Four-pole construction with line and load terminals simplifies wiring and delivers true three-phase protection. Business impact: reduces cabinet space, speeds up installation, and enhances maintenance safety through clear wiring paths and standardized terminations. Application: well-suited for industrial automation enclosures, motor control centers, and equipment that demands reliable phase isolation. Feature: 80 A rating with 600 Vac and 250 Vdc, plus 50/60 Hz compatibility, enables broad use across mixed-voltage equipment. Business impact: lowers spare parts inventory and expands panel compatibility in automation cells and data centers. Application: ideal for new builds and retrofits within facilities that run mixed AC/DC power rails and variable frequency drives. Feature: High interrupt ratings of 85 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 18 kAIC at 600 Vac provide robust fault-current management. Business impact: safer starts, reduced arcing, and improved uptime for heavy equipment, robotics, and packaging lines operating near crest current events. Application: essential where large motor loads demand quick, predictable isolation. Feature: Certifications and compliance—IEC rated, CSA certified, UL listed, CE marked—support global deployment and regulatory clearance. Business impact: accelerates procurement, simplifies cross-border panel fabrication, and strengthens customer confidence by aligning with recognized standards and market requirements. Feature: Series G, JG frame, complete breaker design with line-load terminals offers straightforward installation, easy retrofits, and reliable serviceability. Business impact: minimizes field rework, reduces panel downtime during upgrades, and extends the life of capital equipment in electrical protection schemes for plant-wide safety.
