Product Description:

The 132H2244 is an AC motor starter module manufactured by Danfoss and positioned in the MCD Soft Starters series. It governs the voltage applied to squirrel-cage induction motors during startup, reducing electrical stress on the supply and mechanical shock on the driven load. By providing controlled acceleration and deceleration, the device helps conveyors, pumps, and process fans reach steady speed without large current peaks or sudden torque changes. That softer transition can reduce belt slip, pressure surges, and abrupt load changes during motor starts and stops.

The starter is engineered for machines that draw up to 160 A of line current. It connects directly to mains circuits rated from 380-690 V AC, making it suitable for industrial supply systems in that voltage range. The control section accepts a signal of 24 V AC/V DC, allowing interface with PLC outputs or hard-wired push buttons. Because the unit uses three-phase power, it synchronizes thyristor firing across all three legs to keep phase balance during ramp-up and ramp-down. Its non-bypassed design keeps the thyristors in the current path after the start cycle, so enclosure ventilation and upstream protection should account for continuous conduction losses during operation.

In compact control centers, the open chassis has an IP00 rating, so it must be installed inside a ventilated enclosure with suitable guarding against accidental contact. The standardized frame size 2 outline supports straightforward mounting where that mechanical format is already used, and it can help preserve existing panel spacing. The unit is part of the VLT Soft Starter MCD group, and the open structure leaves the power section accessible for panel wiring and inspection. This design is intended for protected cabinet installation rather than direct exposure to dust, debris, or water.
