CDM1L-100M/4300B Molded Case Leakage Protection Circuit Breaker (English Version)
The CDM1L-100M/4300B molded case leakage protection circuit breaker is a multifunctional protective device developed for low-voltage distribution systems. Designed for AC 50Hz circuits with rated operational voltage up to 400V and rated current of 63A, this unit integrates overload protection, short-circuit protection, and earth leakage protection into a compact modular assembly, providing comprehensive safety for electrical equipment and personnel.
Constructed with high-strength thermosetting materials through integral molding process, the breaker features a precision electromagnetic trip mechanism and bimetal thermal protection system. Its 4-pole configuration (4300B) enables synchronous monitoring of three-phase lines and neutral conductor. The adjustable earth leakage protection module allows graded tripping current settings from 30mA to 500mA, adaptable to diverse environmental requirements. A transparent inspection window facilitates visual status confirmation, while the ergonomic operating handle provides clear switching position indication.
During leakage faults, the device achieves circuit interruption within 0.1 second, maintaining tripping current accuracy within ±10%. The instantaneous trip mechanism for short-circuit protection delivers reliable breaking performance. Integrated mechanical interlock prevents mishandling, and plug-in terminal design simplifies installation. The advanced arc extinguishing system effectively suppresses operational overvoltage and reduces contact erosion.
This model suits various applications including industrial plants, commercial buildings, and residential power distribution systems, functioning as main circuit protection or motor protection. Recommended installation environment should maintain ambient temperature between -25℃ to +60℃ with relative humidity below 95%. Routine maintenance requires periodic functional verification through built-in test button and surface cleaning. Professional electricians should perform installation with proper terminal torque application.
