Danfoss 134N9357 VLT Soft Starter MCD50469BT5G4X00CV2 soft starter for controlled starting and stopping of industrial three-phase motors with 469 A operational current.
The Danfoss 134N9357, also identified as the MCD50469BT5G4X00CV2, is a heavy-duty VLT® Soft Starter MCD 500 engineered for the controlled starting and stopping of high-power three-phase induction motors. As part of the proven Danfoss MCD 500 series, it delivers intelligent motor protection, adaptive acceleration control and reliable performance for demanding industrial applications.
Designed for continuous industrial operation, the MCD 500 series reduces electrical inrush current while minimising mechanical stress on motors, gearboxes, belts and driven equipment. Integrated bypass technology, advanced monitoring and programmable motor protection help maximise equipment availability while reducing maintenance requirements.
With a 469 A current rating, three-phase 380-525 V AC supply and integrated bypass contactor, the Danfoss 134N9357 is ideally suited to heavy-duty pumps, compressors, conveyors, crushers, 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 mechanical shock. This improves system reliability, extends equipment life and lowers maintenance costs for motors and driven machinery operating in demanding industrial environments. The Danfoss VLT® Soft Starter MCD 500 range is widely used where dependable motor protection and controlled starting are essential.
With intelligent motor protection, programmable control functions and comprehensive diagnostics, the MCD 500 series integrates seamlessly into industrial automation systems across manufacturing, mining, utilities and process industries.
