CDM3-400N/4300A 350A Molded Case Circuit Protection Device Technical Overview
The CDM3-400N/4300A 350A molded case circuit protection device delivers intelligent power management for modern electrical systems. Designed for AC 50Hz networks with operational voltages up to 690V, this solution integrates multiple protection functions including overload prevention, short-circuit interruption, and circuit isolation within a compact housing. Its multi-layered safety architecture ensures reliable power distribution while maintaining operational flexibility.
Featuring a monobloc thermoplastic enclosure with reinforced insulation properties, the device incorporates precision-engineered electromagnetic trip mechanisms paired with an advanced arc-quenching system. The triple-position indicator (ON/OFF/TRIPPED) provides immediate operational status recognition. Adjustable thermal-magnetic tripping units enable customized configuration for time-delayed overload protection and instantaneous short-circuit response, adaptable to diverse application requirements.
This protective device finds extensive application in industrial plants, commercial complexes, and critical infrastructure for main circuit protection. Suitable for motor protection circuits, transformer secondary protection, and cable line safeguarding, the standard 4-pole (3P+N) configuration supports 350A rated current with competitive breaking capacity. Modular side-mounted accessories including shunt releases and auxiliary contacts facilitate integration with automated control systems. Universal rail-mount design accommodates vertical or horizontal installation in various panel board configurations.
Technical Highlights:
• Modular contact system reduces maintenance downtime by 30%
• Double-breakpoint arc control technology enhances interruption reliability
