Technical Description
The CDM6S-400L/3320 molded case circuit breaker is a premium protection device for AC 50Hz distribution systems up to 415V. With 315A current rating and plug-in rear connection design, it features tool-free installation and space-saving cabinet integration. The thermal-magnetic trip unit provides three-stage protection (L-S-I characteristics) for selective coordination with downstream devices. Its modular construction includes interchangeable trip units and accessories, while the insulated housing meets stringent non-combustibility requirements.718
Functional Advantages
This breaker adopts precision-engineered contact system with silver alloy tips, ensuring low contact resistance and extended electrical life. The rotary operating mechanism guarantees consistent switching performance even after prolonged use. Optional communication modules enable remote monitoring of operational status. For motor applications, its adjustable magnetic trip threshold (6-12xIn) reliably discriminates between startup surges and fault currents. The compact footprint (76mm width for 3P) allows high-density panel layouts.212
Typical Applications
Ideal for main distribution boards and sub-panel protection in factories, commercial complexes and renewable energy plants. The 50kA breaking capacity (at 415V AC) makes it suitable for installations with high prospective short-circuit currents. When used with RCD modules, it provides comprehensive protection against earth faults. The product s vibration-resistant design meets marine and mining equipment requirements. Horizontal mounting capability facilitates side-by-side installation in narrow spaces.19
