English Introduction
The CDM3L-160F/4300B 125A 1/3/5 Delay 1 Molded Case Earth Leakage Circuit Breaker is a comprehensive protection device designed for low-voltage distribution systems, suitable for AC 50Hz circuits with rated operational voltage up to 400V. Integrating overload protection, short-circuit protection, and earth leakage monitoring functions, this product effectively enhances electrical safety and system reliability, making it adaptable to industrial controls, commercial buildings, public facilities, and residential applications.
Featuring modular construction, the housing is molded from high-strength engineering plastics combined with flame-retardant materials, achieving optimal insulation and mechanical durability. The internal mechanism incorporates precision electromagnetic trip units and electronic leakage detection modules for real-time current anomaly monitoring. During overload or short-circuit conditions, the breaker interrupts fault currents within milliseconds. Its sensitive differential current detection technology rapidly identifies leakage signals, triggering protective actions to mitigate electric shock risks and fire hazards.
Key specifications include a 125A rated current, compatibility with three-phase four-wire systems (denoted by 4300B), adjustable earth leakage trip thresholds (1/3/5 selectable ranges), and 1-stage time-delay characteristics to balance protection accuracy and equipment coordination. The robust breaking capacity ensures reliable tripping under severe short-circuit conditions. The energy-storing operating mechanism provides crisp switching actions, with a color-coded handle position indicator for instant status recognition.
User-friendly design elements include dual mounting options (DIN rail or bolt fixation), anti-loosening terminals accommodating copper conductors up to 35mm², and an IP40-rated enclosure with anti-aging treatment for reliable performance across -25℃ to +70℃ environments. Periodic functional testing is recommended based on operational conditions to maintain optimal protection performance.
