Feature: Glass fiber loop sensor enables EMI-resistant arc detection along a 35 m loop. Business Impact: This configuration improves monitoring reliability, reduces nuisance trips, and minimizes false alarms caused by electrical noise in harsh industrial environments. Application: It is well suited for large switchgear banks, retrofit projects, and facilities with tight spaces where routing a conventional sensor would be challenging. Feature: Light sensing type uses fiber with 8000 Lux sensitivity. Business Impact: High sensitivity ensures arc flashes are detected even under variable lighting or obstructed views, enabling faster protective actions. Application: Suitable for manufacturing floors, data centers, and processing plants with dense cabinets and protective zoning needs. Feature: Extended 35 m fiber loop length reduces the need for multiple sensors. Business Impact: Cuts installation time, parts, and wiring costs while enabling centralized protection logic. Application: Ideal for multi-bay panels and distributed feeders in large electrical installations. Feature: UL Recognized and cUL Recognized certifications support compliance. Business Impact: Simplifies procurement across North America and supports OEM integration with confidence in safety standards. Application: Fits regulated environments and projects requiring recognized protection modules. Feature: Standard warranty and service policy. Business Impact: Provides long-term value with assurance of replacement or service within one year of installation or 18 months from shipment. Application: Reduces total cost of ownership and stabilizes maintenance planning.
