Feature → Business Impact → Application. Feature: Electronic LSI trip enables precise, accelerated fault sensing and selective coordination, reducing nuisance trips and improving system availability. Business impact: With improved coordination, maintenance windows shrink and fault diagnostics become faster, lowering total cost of ownership. Application: This is ideal for underground mining control circuits and other high-current feeders where reliable trip curves are critical. Feature: 800 A amperage rating and three-pole N-frame design provides robust protection for large mining feeders. Business impact: Simplifies panel design, supports scalable protection, and reduces alternative equipment costs by consolidating protection devices. Application: Use in main feeders and motor circuits in mining operations requiring high-current protection. Feature: 600 Vac voltage rating with interrupt ratings of 25 kAIC at 600 Vac, 50 kAIC at 480 Vac, and 65 kAIC at 240 Vac. Business impact: Delivers versatile protection across common mining voltages, improving reliability and compliance across cascaded systems. Application: Suitable for mixed-voltage underground and surface equipment where fast clearing is needed. Feature: Undervoltage release of 120 Vac mining rear with left pigtail simplifies wiring and control integration. Business impact: Reduces installation time and wiring errors, enhancing safety in hazardous mining zones. Application: Control circuit and alarm interlocks in underground panels. Feature: UL Listed and CSA Certified along with Digitrip-style electronic trip options support regulatory compliance and industry-standard maintenance. Business impact: Eases procurement, audits, and service planning while improving safety margins. Application: Procurement for regulated mining sites and multi-site installations requiring certified protection.
