Product Description:
The 175G5224 is a solid-state soft starter manufactured by Danfoss as part of the MCD Soft Starters series. It belongs to the VLT Soft Starter MCD group and the 202 model class, and it is installed between the line supply and an induction motor to moderate the applied voltage during startup. By controlling the rate of rise of current, it reduces mechanical shock and electrical stress in conveyors, pumps, and similar automated loads. This soft-start method helps protect couplings, belts, and driven equipment during repeated starts.
A low-voltage control circuit accepts 24 VAC/VDC, energizing the internal logic and gate drives that control the main thyristors. The power section accommodates mains from 200-440 VAC and uses an A-frame mechanical footprint for compact panel layouts. Under continuous duty, the starter carries a normal line current of 60 A, while a heavy-duty setting supports up to 49 A for demanding acceleration profiles. Thermal and conduction limits allow the unit to switch motors up to 30 kW without exceeding junction limits. Control-side inrush current is 2 A, and the integrated main contactor is rated 6 A at 250 VAC for bypass or isolation functions after the motor reaches full speed. This arrangement limits heat generation once acceleration is complete. Its compact form helps fit the unit into crowded panels where starter spacing is limited.
Electrical protection is provided by an enclosure rated IP20, which is suitable for installation inside a clean control cabinet. The dedicated start input tolerates up to 300 VAC, allowing direct linkage to high-level control signals without additional relays. It is designed for three-phase power networks, where synchronized phase firing helps maintain balanced line currents and consistent torque production. This arrangement helps maintain smoother motor acceleration on variable process loads. Programmable ramp and kick-start parameters allow the soft starter to match acceleration behavior to the connected load while reducing line disturbances.
