【English Version】
The CDM3L-630N/4300A 400A 1/3/5 Delay 3 Molded Case Leakage Protection Circuit Breaker is an intelligent protection device designed for low-voltage power distribution systems. Its core function lies in real-time monitoring of leakage, overload, and short-circuit faults in circuits, with rapid power interruption to ensure electrical safety. Featuring a modular structural design, the product combines compact dimensions with high breaking capacity, making it suitable for industrial, commercial, and residential power distribution protection requirements.
With a rated current of 400A, this circuit breaker is compatible with three-phase four-wire or three-phase five-wire distribution networks and supports multi-level interlock protection mechanisms. The built-in leakage detection module accurately identifies residual currents in circuits. When detected values exceed preset thresholds, the device initiates tripping within milliseconds, effectively reducing risks of electrical fires and electric shocks. For diverse application scenarios, the product offers three-stage delay protection (1/3/5 Delay 3), allowing users to flexibly adjust activation parameters based on actual load characteristics, balancing protection sensitivity and system stability.
Structurally, the enclosure utilizes high-strength engineering plastics combined with flame-retardant materials, significantly enhancing resistance to high temperatures and mechanical impacts. The contact system employs multi-channel arc-extinguishing technology to ensure high short-circuit breaking capacity while extending electrical service life. Installation options include rail mounting or bolt fixation, compatible with standard distribution cabinet layouts. The user interface features an intuitive status indicator window and a reset button for simplified maintenance and troubleshooting.
This product is widely applicable to factory production lines, commercial complexes, data centers, and residential distribution boxes, providing reliable protection for transformers, motors, cable lines, and other equipment. Through optimized electromagnetic compatibility design, it ensures stable operation in complex grid environments while minimizing false triggering risks. The streamlined mechanical structure and standardized terminal design further enhance installation efficiency and long-term operational reliability.
