WEEE Category
5. Small Equipment (No External Dimension More Than 50 cm)
Feature: 4-pole design delivering 80 A and 500 V DC operating capability. Business Impact: provides synchronized protection across all poles, enabling faster fault interruption and reducing arc energy in rugged DC networks. Application: ideal for DC distribution in industrial control panels, motor drives, data-center infrastructure, and battery storage installations where reliable 4P protection is critical. Feature: Short-circuit withstand ratings—(250 V DC) 100 kA for two poles in series and (500 V DC) 50 kA for three poles in series. Business Impact: limits fault propagation, minimizes equipment damage, and supports safe reclosing in demanding services. Application: renewable energy inverters, DC bus ties, mezzanine power modules, and high-energy control circuits where fast dissipation matters. The high Ics/Icu figures give designers confidence in panel protection without oversizing components. Feature: Power loss of 5.8 W per pole and 25,000 mechanical cycles. Business Impact: reduces standby energy consumption, lowers operating costs over the product lifecycle, and provides predictable performance under continuous duty. Application: battery-backed DC rails and industrial PCs in manufacturing lines where reliability is mission-critical. The 25k durability specification also supports extended maintenance intervals and reduced spare-part consumption. Feature: Fixed terminal connection type and a Tmax XT2 TM release with 4P configuration. Business Impact: simplifies panel wiring, minimizes field errors, and speeds commissioning through modular installation and standardized mounting. Application: control cabinets, machine builders’ panels, and modular power distribution units that require fast, repeatable assembly. Feature: EcoSolutions alignment with an Environmental Product Declaration (EPD), RoHS and REACH compliance, and a recyclability rate of 55.7% per EN45555. Business Impact: strengthens sustainability reporting, supports regulatory compliance, and lowers end-of-life costs via design-for-closing-resource-loops. Application: projects with green procurement targets, data centers seeking green certification, and automotive or energy installations prioritizing responsible material management.
