Selling Policy 25-000 - Distribution and Control Products and Services
Feature: Four-pole, complete KD-frame breaker simplifies DC protection for PV systems. Business Impact: Reduces wiring complexity and improves fault isolation, enabling faster commissioning and easier field maintenance with a single, integrated protection device. Application: Ideal for PV string combiner boxes, outdoor solar stations, and equipment racks where consistent performance and compact footprint matter. Feature: 200 A amperage rating and 1000 Vdc rating. Business Impact: Enables direct protection of large PV arrays and inverters without cascading multiple devices, reducing interconnect length, wiring errors, and enclosure space. Application: Suitable for commercial and utility‑scale solar projects with higher DC bus voltages in rooftops and ground mounts. Feature: 5 kAIC interrupt rating. Business Impact: High fault-current tolerance minimizes equipment damage, reduces downtime, and extends inverter and transformer life. Application: PV farms, DC switching stations, and battery-backed solar arrays where fault currents can peak. Feature: Fixed thermal and fixed magnetic trip (T186) with 50°C calibration. Business Impact: Delivers precise protection across typical PV site temperatures, reducing nuisance trips and maintaining consistent response as ambient conditions vary. Application: Outdoor solar installations in climates up to 50°C ambient. Feature: Without terminals. Business Impact: Simplifies enclosure design by allowing terminals to be provided by upstream devices or bus bars, saving install time and reducing field wiring complexity. Application: Use where upstream lugs or connectors are installed in the enclosure. Feature: CSA Certified and UL Listed; PV class. Business Impact: Streamlines procurement, regulatory approvals, and safety validation for North American projects. Application: Suitable for utility-scale and commercial PV installations requiring local code compliance. Feature: PV Class and 50°C rating with 80% rated setting. Business Impact: Confidence in sustained operation in typical site conditions, reducing derating surprises. Application: Outdoor PV installations with elevated temperatures.
