MCI DOL, CI-tronic contactors - DANFOSS INDUSTRIAL AUTOMATION

MCI DOL and CI-tronic contactors from Danfoss Industrial Automation are high-performance electromechanical switching devices designed for direct-on-line motor starting and general load management in industrial control panels. These contactors feature robust coil systems with wide voltage ranges (e.g., 24-240V AC/DC), integrated surge suppression, and mechanical interlocking options for reversing applications. The CI-tronic series includes electronic coil control for reduced power consumption and extended electrical life, with ratings typically from 9A to 65A at 400V AC. They are available in 3-pole and 4-pole configurations, with optional auxiliary contact blocks and thermal overload relays for comprehensive motor protection.

These contactors are primarily used in motor control centers (MCCs), conveyor systems, pump stations, HVAC equipment, and industrial automation lines where reliable switching under frequent start/stop cycles is required. They are also suitable for lighting control, resistive loads, and capacitor bank switching in commercial and industrial electrical installations. Their compact design allows easy integration into standard DIN rail or panel-mounted enclosures.

Key subcategories include the MCI DOL series for direct-on-line starters and the CI-tronic series with electronic coil management. Main article codes follow patterns like MCI DOL 9, MCI DOL 12, MCI DOL 18, MCI DOL 25, MCI DOL 32, MCI DOL 40, MCI DOL 50, MCI DOL 65, and CI-tronic 9, CI-tronic 12, CI-tronic 18, CI-tronic 25, CI-tronic 32, CI-tronic 40, CI-tronic 50, CI-tronic 65, where the number indicates the rated operational current in amperes at 400V AC-3. Accessories include auxiliary contact blocks (e.g., CA4-22, CA4-11) and thermal overload relays (e.g., TA25, TA32, TA40, TA65).
