Product Description:

The 175G5232 is a soft starter assembled by Danfoss within the MCD Soft Starters series and classified under the VLT Soft Starter MCD product group. Identified in the platform as model MCD 202, the unit manages motor acceleration and deceleration in three-phase automation lines, preventing mechanical shock and reducing electrical stress on connected equipment. By controlling the initial voltage applied to the motor, it limits torque peaks and extends component life while integrating with standard control panels through its dedicated control supply of 110/240 VAC or 440 VAC. This operating method is well suited for conveyors, pumps, fans, and similar machinery that benefits from smoother starts and controlled stopping behavior.

The power section accepts a mains input from 200-575 VAC, allowing a single model to be deployed on varied distribution networks. Logic circuits draw under 100 mA once the starter reaches run state. Under 40 °C ambient, the unit supplies a heavy-duty current of 30 A for infrequent high-torque starts or a normal-duty current of 34 A for repetitive loads. Its across-the-line replacement capability supports motors up to 7 kW, and only 10 A of inrush current is seen during each soft ramp. The enclosure carries a protection rating of IP20, so live parts remain finger-safe when the device is panel-mounted in ventilation-controlled environments. Reduced current demand during startup also helps ease stress on upstream electrical components and connected drive equipment.

Packaged in an A-Frame housing, the starter occupies a depth of 165 mm, a width of 98 mm, and a height of 203 mm, enabling high-density installation on DIN rails or backplates. It weighs just 2.4 kg, so the unit is easy to mount in compact control cabinets. The solid-state path withstands fault energy up to 5 kA, while a thermistor cutout set at 2.8 kΩ protects connected motor windings from overheating. Designed for three-phase power, the device keeps internal losses low by switching to a bypass contactor once full speed is achieved. That arrangement also reduces heat buildup during steady running and helps preserve service life in continuous-duty applications.
