Product Description:
The 175G5249 is a soft starter manufactured by Danfoss as part of the MCD Soft Starters series. It belongs to the 202 sub-series inside the VLT Soft Starter MCD product group. Installed between a three-phase supply and an induction motor, the unit ramps voltage smoothly to curb mechanical shock and electrical transients at start-up. Its B-Frame format keeps the footprint small enough for typical pump, fan, and conveyor panels.
The control electronics accept 24 VAC/VDC, allowing the starter’s logic to remain energized even when the main circuit is isolated. During the first half-cycle, the control circuit draws only 2 A, minimizing the load on auxiliary power supplies. The main power section handles line voltages from 200-575 VAC, so one model can support mixed plant grids. For high-torque applications, the heavy-duty rating permits a steady motor current of 96 A, whereas standard centrifugal loads run under the normal-duty limit of 100 A. These ratings correspond to class AC53b 4-6:594, which indicates thermal cycling limits for repetitive starts. A built-in main contactor and B-Frame mounting holes support straightforward installation without extra hardware.
The starter is sized for motors up to 55 kW and withstands prospective fault levels of 10 kA on the line side. Its enclosure carries an IP20 rating, so it must be installed inside a cabinet but requires no additional finger-safe barriers. Net shipping mass is only 4.3 kg, easing panel door installation. The main contactor and the programmable relay both switch 6 A at 250 VAC, matching typical PLC output cards. Phase imbalance protection trips at 30% with a 3 s delay to guard against single-phasing, and mechanical life is rated for 1,000,000 operations to support long service intervals.
