Product Introduction
The DELIXI CDM3L-630F/4300B molded case leakage circuit breaker is a high-performance protection device designed for industrial power distribution systems, suitable for 400A current rating in three-phase four-wire circuits. Its modular design features three-stage protection characteristics (with selectable 1/3/5/10 second delay), effectively identifying leakage, overload and short-circuit faults to ensure safe operation of electrical equipment. The compact plastic housing facilitates installation while adapting to various panel layouts.724
Key Features
Adjustable residual current protection (100/300/500mA three-range) combined with multi-level delay settings (0.1-10s) precisely matches diverse application requirements. The thermal-magnetic trip mechanism ensures rapid circuit interruption during faults, with 50kA breaking capacity. The openable neutral pole enhances wiring flexibility, and front-mounted installation simplifies construction. The visible breakage indicator provides clear operational status for troubleshooting.1318
Technical Specifications
Rated operational voltage AC 400V, frame current 630A supporting 400A rated current configuration. Leakage protection response time ≤0.2s (3 adjustable ranges), mechanical endurance exceeds 10,000 cycles. Eco-friendly flame-retardant housing meets industrial requirements for high temperature and impact resistance. Specially designed arc-extinguishing system suppresses switching overvoltage to protect downstream equipment. Phase imbalance protection prevents equipment damage caused by phase loss.925
