Product Description:

The 175G5221 from Danfoss stands in the MCD Soft Starters line and keeps things running smoother for machines needing less punch at startup. A power rating of 15 kW sits at the heart, offering enough grunt for medium industrial jobs without jumping all at once. The maximum rated current clocks in at 34 A, built for runs with a steady load and no unexpected cuts. With operating mains voltage ranging from 200–440 VAC, a wide band works with various setups where voltages bounce around. The frequency sits between 45–66 Hz — useful for different regions or supply conditions.

The body of this soft starter is compact, measuring 203 x 98 x 163 mm, which is good news for cabinets that don’t have much open space left. There’s an IP20 protection badge, so nothing bigger than a finger sneaks inside, keeping accidental contact away but best used in sheltered panels, not direct lines of dust or splash. For protection in tougher places, usually, something more is needed, but for inside cabinets, this does the job. The gross weight is 2.9 kg, which is light enough not to break shelves or rack mounts during setup. Both frame size A and manageable weight mean lifting or swapping out goes quick. A net weight of 2.4 kg keeps shipping cost just right and less hassle for field installs.

On top, a control supply voltage of 24 VAC/VDC gives wiring flexibility. There’s an allowed ±20% control voltage tolerance, so brief dips don’t always knock things out. When startup heat builds, max power loss at start sits under 3 W per amp while power loss in operation stays below 4 W, keeping things cool and power wasted low.
