Product Description:
175G5535 is a part of Danfoss VLT MCD 500 soft starter series which assigns the product to a proven motor starting family and clarifies application class. The nominal current in-line is 255 A which defines the continuous current the starter must carry and determines cable and protection sizing. Its nominal current inside delta is 383 A which increases available motor capability and guides internal wiring and thermal planning.
This AC-53b duty (bypassed) is 255 A that sets the bypassing contact short time duty and dictates fuse and busbar ratings. Further, the AC-53a duty (non-bypassed) is 245 A which defines the continuous motor switching rating when power semiconductors remain in the circuit. Supply voltage range for the controller is 200-690 VAC, permitting use across wide industrial mains. The maximum start current specification of 400 percent FLC for 20 s indicates permitted high current duration during prolonged starts and sets thermal stress limits. Short-circuit withstand (SCCR) is 65 kA at 600 V which defines prospective fault energy the starter can tolerate and influences panel SCCR design. Furthermore, its max fuse size is AJT300 Class J RK1 and min/max FLC setting in-line is 51-255 A.
The 175G5535 soft starter displays min/max FLC setting inside delta as 77-382 A that establishes the selectable range for delta-connected motors and affects internal current transformer selection. Ambient operating temperature range is -10°C to +60°C which determines enclosure climate control. The external bypass contactor required is set to “Yes”, which means an auxiliary contactor must be provided for certain installations and wiring. Enclosure rating of IP20 indicates protection against finger contact only and requires an enclosed cabinet for dusty or wet environments. The model employs Adaptive Acceleration Control and mains frequency compatibility 45-66 Hz, supporting multiple regional power systems and allows flexible deployment.
Frequently Asked Questions about 175G5535:
Q: What supply voltage band does the 175G5535 support?
A: The supply voltage range is 200-690 VAC. The device allows connection to a broad set of industrial mains without a step transformer.
Q: How long is the maximum permitted high start current for the 175G5535?
A: The maximum start current condition is 400% FLC sustained for 20 s. This defines the allowable peak current multiple and the maximum duration for a single prolonged start.
Q: What short-circuit withstand rating applies to the 175G5535?
A: The short-circuit withstand (SCCR) is 65 kA at 600 V. This rating indicates the prospective fault current the starter assembly can tolerate during a fault and affects panel and fuse coordination.
Q: What is the maximum fuse size recommended for the 175G5535?
A: The maximum fuse type specified is AJT300 Class J RK1 for this soft starter. It defines the branch protection recommended for the starter.
Q: What in-line FLC adjustment range is available for the 175G5535?
A: The module’s min/max FLC setting in-line is 51-255 A. This adjustable range defines the starter’s configuration window for inline motor full load current settings.
