The CDM6LI-160M/4300B 140A 03/1/3 Molded Case Leakage Circuit Breaker is a safety protection device specifically designed for low-voltage distribution systems, suitable for three-phase four-wire networks with a rated current of 140A. Featuring modular construction, it integrates earth leakage protection, overload protection, and short-circuit protection functions, effectively monitoring circuit abnormalities and promptly interrupting fault currents to ensure reliable protection for electrical equipment and personnel safety.
The product s core advantages lie in its intelligent detection and rapid response capabilities. Equipped with precision electronic components, it continuously monitors residual current variations in circuits. When detecting leakage currents reaching preset thresholds, it completes circuit interruption within 0.1 seconds. The bimetal thermal-magnetic trip mechanism provides graded protection against overload and short-circuit faults, effectively preventing false operations while ensuring rapid circuit disconnection under extreme conditions. The high-strength engineering plastic housing offers excellent flame resistance and impact resistance, with IP40 protection rating suitable for humid and dusty environments.
A transparent mechanical status indicator window with red-green color coding enables visual confirmation of device status. The energy-storing operating mechanism ensures stable switching operations with uniform handle operation force, effectively extending mechanical service life. Copper alloy terminals with optimized surface treatment support secure connections for conductors up to 35mm², maintaining long-term contact reliability.
This circuit breaker is particularly suitable for power distribution system upgrades in industrial plants, commercial buildings, and infrastructure projects, especially where critical equipment such as motors and transformers require leakage protection. Compatible with both DIN rail mounting and fixed installations, it facilitates integration into various switchboard designs. The built-in test button allows regular functional verification to ensure sustained operational reliability during maintenance cycles. Its compact structure and ergonomic design simplify installation while maintaining high performance in space-constrained environments.
