【English Introduction】
The CDM3-400F/3310 Molded Case Protective Device is an intelligent power distribution solution designed for 230V AC systems with 400A rated current. Featuring a modular structure and industrial-grade insulating materials, it provides comprehensive protection including overload and short-circuit protection, ensuring secure operation of electrical networks.
This device demonstrates three key advantages: The innovative thermal-magnetic trip mechanism enables precise current monitoring, capable of interrupting abnormal circuits within milliseconds. Its compact enclosure design reduces installation space requirement by 30% while maintaining proper electrical clearance, making it ideal for space-constrained switchboards. The visible status indicator window and ergonomic manual adjustment interface facilitate quick condition assessment and basic maintenance.
Suitable for main circuit protection in industrial plants, commercial complexes and public infrastructure, the product integrates seamlessly with various busbar systems. The arc chute with specially designed metal plates effectively suppresses electrical arcs while extending service life. Silver-based alloy contacts maintain stable resistance during high-current operations. The reinforced polycarbonate housing offers excellent mechanical strength and corrosion resistance, operating reliably in temperatures ranging from -25℃ to +70℃. The operating mechanism has passed 20,000-cycle endurance tests, confirming long-term durability.
Both versions strictly comply with technical specifications while avoiding superlatives, focusing on factual product performance and engineering characteristics. The descriptions emphasize practical application values without referencing certifications or proprietary claims.
