Danfoss VLT Soft Starter MCD 500 MCD50525BT7G4X

Why Choose the Danfoss 134N9363 Soft Starter?

The Danfoss 134N9363, also identified as the MCD5-0525B-T7-G4X-00-CV2, is a heavy-duty VLT® Soft Starter MCD 500 designed to deliver intelligent starting, stopping and protection for large 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 maximise equipment reliability while reducing mechanical and electrical stress.

Engineered for demanding industrial applications, the MCD 500 series significantly reduces motor inrush current while protecting gearboxes, belts, pumps and driven equipment from excessive mechanical shock. Built-in bypass technology, programmable motor protection and intelligent monitoring help minimise downtime and reduce maintenance costs across a wide range of industries.

With a 525 A rated current, three-phase 380-690 V AC supply and an integrated bypass contactor, the Danfoss 134N9363 is ideally suited for high-power conveyors, pumps, compressors, crushers, fans and process machinery operating in demanding industrial environments.
