英文介紹 (Product Description)
The CDM3-400H/3280 400A AC230V molded case circuit breaker is designed for industrial and commercial power distribution systems, providing reliable protection against overloads and short circuits. With a frame current of 400A and rated operational voltage of 230V AC, it features a compact modular structure for easy installation and maintenance. The thermal-magnetic trip unit ensures precise detection of abnormal currents, enabling rapid circuit interruption to minimize equipment damage. Its three-pole (3P) configuration supports balanced or unbalanced three-phase loads, while optional accessories enhance adaptability to diverse electrical environments.
Constructed with flame-retardant engineering plastic, the breaker operates stably within -25℃ to +55℃. The silver-alloy contacts reduce resistance and withstand high arcing, ensuring durability. The ergonomic handle and mechanical status indicators simplify operation and monitoring. Ideal for motor protection, transformer circuits, and distribution panels, it integrates seamlessly into fixed or withdrawable switchgear with optimized thermal management for continuous performance. 3815
