Product Description:
175G5217 is a top-product from Danfosslatest MCD soft starter series. The device uses 75 kW power and signifies the maximum continuous motor power and guides motor selection, protection sizing and thermal management in panel design. Its rated current of 140 A sets the continuous electrical load limit and informs cable sizing and overload protection for safe operation. The unit’s 3-phase operation provides balanced power delivery for industrial motors and thus supports higher torque capacity and smoother drive performance compared with single phase systems.
Main voltage range is 200 to 440 VAC which allows connection to common industrial supplies without step conversion and reduces field adaptation. The control voltage accepts 110/240 VAC or 440 VAC, supporting multiple control architectures and easing integration with plant control transformers. Size of C-Frame defines chassis layout and affects enclosure spacing. The part number is a soft starter which ramps voltage to limit inrush current and reduces mechanical stress on driven equipment. The module’s heavy start duty at 4 x Ie for 20 seconds specifies prolonged start capability and clarifies thermal limits for high load starts. Its normal start duty at 4 x Ie for 6 seconds indicates short term starting capacity for frequent cycles. Mounting supports DIN rail installation up to 30 kW which enables compact cabinet layouts for smaller systems.
The 175G5217 offers compatibility with grounded delta power systems to determine acceptable earthing and connection schemes for installation. The drive’s net weight of 6.8 kg and gross weight of 7.6 kg allow shipping calculations and mounting load on rails and panels. With an integral bypass function, it bypasses SCRs during run to reduce heat dissipation and lower cooling requirements inside the enclosure. The design supports installation within non-ventilated enclosures, reducing the need for forced ventilation and affects cabinet thermal planning.
Frequently Asked Questions about 175G5217:
