CDM6LI-125C/4300A 50A 03/1/3 Molded Case Residual Current Circuit Breaker
Product Overview
The CDM6LI-125C/4300A 50A 03/1/3 is a molded case circuit breaker integrating overload, short-circuit, and earth leakage protection functions, designed for terminal circuit protection in low-voltage distribution systems. Featuring modular construction with three-stage protection characteristics, it effectively prevents electrical accidents caused by circuit abnormalities. The high-strength engineering plastic housing ensures reliable insulation and mechanical durability.
Key Features
Equipped with intelligent tripping mechanism, the device accurately detects 30mA leakage current and interrupts circuits within 0.1 seconds. The 4-pole linkage structure (03/1/3) ensures synchronized phase-neutral disconnection while maintaining independent grounding protection. With 50A rated current and 4300A breaking capacity, it adapts to various distribution environments. The optimized arc-extinguishing system rapidly quenches fault arcs, minimizing contact wear. Multi-color status indicators under the transparent cover provide visual confirmation of operation states and fault types.
Structural Advantages
The compact housing design saves 25% installation space compared to conventional models. Rotary terminals accept direct connection of conductors up to 35mm². Bimetallic strip and electromagnetic release cooperate to ensure precise tripping coordination. Silver-alloy moving contacts combined with honeycomb arc chute design enhance electrical endurance. Ergonomically designed operating handle delivers clear position feedback with ≤4N·m switching torque.
Application Scope
Suitable for residential distribution boxes, commercial lighting circuits, industrial control panels, particularly recommended for humid environments, temporary power supplies, and critical equipment protection. Compatible with multiple DIN rail types, supporting vertical or horizontal mounting.
