Danfoss 175G5501 VLT Soft Starter MCD50037BT5G1X20CV1 soft starter for controlled starting and stopping of industrial three-phase motors with 37 A operational current.
The Danfoss 175G5501, also identified as the MCD5-0037B-T5-G1X-20-CV1, is a compact VLT® Soft Starter MCD 500 engineered to provide intelligent motor starting, stopping and protection for three-phase induction motors. As part of the advanced Danfoss MCD 500 series, it combines adaptive acceleration control, integrated motor protection and comprehensive diagnostics to improve equipment reliability while reducing electrical and mechanical stress.
Designed for industrial automation and OEM machinery, the MCD 500 series significantly reduces motor inrush current and minimises mechanical shock to motors, couplings, gearboxes and driven equipment. Its integrated bypass technology and programmable motor protection help maximise system uptime while lowering maintenance costs.
With a 37 A rated current, three-phase 200-525 V AC supply and a 24 V AC/DC control supply, the Danfoss 175G5501 is ideal for pumps, conveyors, compressors, fans and other industrial machinery requiring dependable soft starting performance.
Soft starters gradually increase the voltage supplied to a motor during start-up, reducing current surges and limiting mechanical shock. This improves equipment reliability, extends service life and lowers maintenance costs while improving overall system performance. The Danfoss VLT® Soft Starter MCD 500 range is widely recognised for intelligent motor protection and dependable industrial operation.
With programmable control functions, integrated bypass technology and comprehensive diagnostics, the MCD 500 series integrates seamlessly into industrial automation systems across manufacturing, utilities and process industries.
