5. Small Equipment (No External Dimension More Than 50 cm)
Feature: High DC protection rating (800 A, 750 V DC) across a 3-pole configuration. Business Impact: Delivers reliable fault isolation for high-current DC networks, reducing unplanned downtime and improving system availability. Application: Data centers and industrial DC bus protection where fast interruption prevents collateral damage. Feature: High short-circuit withstand capabilities (Ics up to 35 kA at 250 V DC; 18 kA at 750 V DC in 3P series) with 70 kA ultimate break capacity at 250 V DC. Business Impact: Ensures selective coordination and robust fault clearance under diverse DC fault conditions, lowering risk of cascading outages. Application: Battery storage systems and motor drives where fault levels vary. Feature: Extended mechanical durability (20,000 cycles; 120 cycles/hour) and low power loss (54.2 W per pole). Business Impact: Longer service life, reduced maintenance costs, and lower energy consumption during normal operation. Application: Frequent switching environments and long lifetime installations. Feature: Environmental and compliance framing (EPD, RoHS, REACH; 60% recyclability per EN45555). Business Impact: Supports sustainability targets and regulatory compliance while reducing lifecycle waste. Application: Green data centers and eco-conscious industrial plants. Feature: Installation and compatibility (Fixed circuit-breakers; dimensions 210 mm x 268 mm x 103.5 mm; weight 9.5 kg). Business Impact: Simplifies panel integration and minimizes mounting effort, accelerating commissioning. Application: Custom electrical panels and retrofit projects where fixed mounting is preferred. Feature: Standards and release details (IEC 60947-2; Release TMA/TM). Business Impact: Ensures global compliance and predictable behavior across installations. Application: International projects requiring certified DC protection.
