1. Incorporate an advanced arc-extinguishing system (E.g., high-efficiency arc-extinguishing grids), and feature an exceptionally high ultimate short-circuit breaking capacity (Icu) and operating short-circuit breaking capacity (Ics), reaching up to 100 kA. 2. Offer multiple wiring configurations, including front-panel, rear-panel, plug-in, withdrawing and other types. Its high-capacity models employ a dual-break structure for an reinforced contact reliability. Some of its models support the front-end visualization for the convenient monitoring of contact status. 3. Utilize wear-resistant alloy contacts and optimized mechanism design to achieve a mechanical life span beyond 20,000 times.
