Product Description:
The 175G5535 is a three-phase soft starter produced by Danfoss for the MCD Soft Starters series. In motor control cabinets, this device inserts a controlled voltage ramp between the line supply and an induction motor, limiting inrush current and reducing mechanical shock during startup. An internal bypass closes once the motor reaches rated speed, removing thyristor losses without requiring external contactors.
The starter has a continuous current capacity of 195 A, so upstream protection and cabling must accommodate its thermal rating. It can be installed on supply systems with an insulation level of up to 690 V AC, enabling direct connection to standard 400 V or 480 V networks while providing margin for transient overvoltage. In-line wiring supports a full-load motor current of up to 200 A, while an inside-delta connection increases the permissible motor current to 300 A. The starter has a prospective short-circuit withstand rating of 65 kA, which must be considered when selecting coordinated circuit protection. The control board provides a 24 V auxiliary output that can supply 200 mA to sensors, and its analog interface supports loads down to 600 Ω. The enclosure has an IP00 protection rating and requires installation within a suitable cabinet. Its total mass of 14.9 kg must be considered when selecting panel supports and mounting hardware.
During fault conditions, the power stage resists an impulse voltage of 4 kV, while the SCR stack sustains 320,000 A²s of let-through energy until upstream protective devices trip. Field wiring clamps must be tightened to 38 Nm to provide secure conductor retention at maximum current. Control relays inside the starter can switch up to 10 A at 250 V AC for loads such as fan contactors or status lamps. The predicted heat dissipation during startup is 4.5 W/A, and this value must be included in enclosure cooling calculations to keep internal temperatures within acceptable limits.
