Danfoss 134N9355 VLT Soft Starter MCD50396BT7G3X00CV2 soft starter for controlled starting and stopping of industrial three-phase motors with 396 A operational current.
The Danfoss 134N9355, also identified as the MCD50396BT7G3X00CV2, is a high-capacity VLT® Soft Starter MCD 500 engineered for the controlled starting and stopping of large three-phase induction motors. As part of the proven Danfoss MCD 500 series, it delivers advanced motor protection, adaptive acceleration control and reliable performance for demanding industrial applications.
Designed for heavy-duty industrial environments, the MCD 500 series reduces electrical inrush current and minimises mechanical stress on motors, couplings, gearboxes and driven equipment. Its intelligent control algorithms, integrated bypass and comprehensive protection features help maximise equipment uptime while reducing maintenance costs.
With a 396 A current rating, three-phase 380-690 V AC supply and an integrated bypass contactor, the Danfoss 134N9355 is ideally suited for high-power 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 minimising 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 series provides intelligent motor protection, programmable control functions and advanced diagnostics, making it an ideal solution for modern industrial automation and process applications.
