【English Version】
The CDM3-400F/33002 250A Molded Case Motor Protection Device is an intelligent protection solution specifically engineered for industrial motor systems, designed for three-phase AC power distribution applications with 250A rated current. Featuring a modular construction, this device integrates multiple protection functions including overload, short-circuit and phase-loss protection, ensuring safe and stable operation of motors and related equipment.
Employing a precision thermal-magnetic bimetal mechanism combined with electromagnetic trip technology, the device achieves rapid response to current variations. With a breaking capacity of 50kA, it can complete circuit interruption within 15ms during short-circuit events. The flame-retardant housing material withstands high temperatures and provides IP40 protection level, maintaining reliable performance in ambient temperatures ranging from -25℃ to +70℃. The three-position visual indicator (ON/OFF/TRIP) enables quick status identification and maintenance operations.
This protection device offers precise current setting adjustment through a rotary knob, allowing continuous calibration within 80%-100% of the rated current value. The specially designed arc-extinguishing system effectively suppresses operational overvoltage and minimizes harmonic interference on power grids. Its compact structure supports both vertical and horizontal mounting configurations, compatible with standard rail installations in various distribution cabinets.
Typical applications include: Motor protection for power equipment such as fans, pumps and compressors; Power distribution system protection in industrial sectors including machinery manufacturing, petrochemical and metallurgical plants; Electrical equipment protection in commercial buildings and infrastructure projects. Regular functional verification using professional testing instruments is recommended, along with maintaining proper ventilation for optimal heat dissipation.
