CDM3-160N/3300 100A Molded Case Circuit Protector (English Version)
The CDM3-160N/3300 100A is a compact protection device engineered for low-voltage distribution systems, integrating modular design concepts with optimized operational reliability. This product delivers essential circuit protection functions while incorporating structural innovations to enhance performance in handling overload and short-circuit conditions.
Featuring a space-efficient construction, the unit maintains standard industry dimensions for seamless integration into conventional distribution panels. Its contact system employs silver-based alloy materials with multi-contact parallel technology, ensuring consistent conductivity during prolonged operation. The instantaneous trip mechanism achieves millisecond-level response, working in conjunction with arc-resistant grid technology to promptly interrupt fault currents and suppress arc propagation. The thermally calibrated bimetal strip provides precise overload protection with ±5% threshold accuracy.
Designed for 380V/50Hz AC systems, this protector is suitable for main circuits and branch line protection in industrial plants, commercial complexes, and public infrastructure. The monocoque housing crafted from high-strength engineering plastics offers IP40 protection, while the internally optimized component layout ensures electromagnetic compatibility for stable long-term operation. The mechanical operating mechanism includes visible position indicators and status locking devices, providing clear operational feedback. Expandable auxiliary contact slots allow convenient integration with smart monitoring modules.
The product incorporates a dual-stage arc extinguishing system with deionization chambers, effectively containing electrical discharges during circuit interruption. Terminal connections support both busbar and cable installations, accommodating conductors up to 50mm². Environmental adaptability covers operating temperatures from -25°C to +70°C and relative humidity below 95%, making it suitable for diverse installation conditions. Regular maintenance intervals exceeding 10,000 mechanical operations ensure reduced lifecycle costs.
