Danfoss VLT Soft Starter MCD 500 MCD51200CT5G5X

Why Choose the Danfoss 175G5520 Soft Starter?

The Danfoss 175G5520 is the highest-capacity VLT® Soft Starter MCD 500 in the G5 frame, engineered for the controlled starting and stopping of very large three-phase induction motors in the most demanding industrial environments. With the type code MCD5-1200C-T5-G5X-00-CV1, this intelligent digital soft starter combines Adaptive Acceleration Control, integrated bypass technology and advanced motor protection to deliver exceptional reliability and performance in high-power applications.

The MCD 500 series is designed to minimise electrical inrush current and mechanical shock during motor acceleration and deceleration. Adaptive Acceleration Control continuously adjusts the motor starting profile to suit the connected load, helping extend the service life of motors, gearboxes, conveyors, pumps and other driven equipment while reducing maintenance costs and improving overall productivity.

With a 1200 A rated operational current, a three-phase 200-525 V AC mains supply and a 24 V AC/DC control supply, the Danfoss 175G5520 is ideally suited to mining operations, heavy process industries, water treatment facilities, marine installations and large-scale manufacturing plants. The integrated bypass contactor significantly reduces heat generation and energy losses once the motor reaches full operating speed.

Reliable Motor Control for Critical Industrial Applications

The Danfoss MCD 500 gradually controls the voltage supplied to the motor during acceleration and deceleration. This significantly reduces starting current, torque shock and mechanical wear, protecting motors and driven equipment while improving operational reliability across demanding industrial installations.

Its intelligent protection functions continuously monitor overload, phase imbalance, phase loss, excessive start time, motor temperature and supply conditions, helping maximise uptime and protect valuable industrial assets.
