Overview

The Danfoss VLT® Soft Starter MCD 600 (SKU: 136Z4309) is a high-performance industrial soft starter designed for fixed-speed applications where precise motor control is critical. Rated for 350 HP (590 A continuous) at 200-525 V mains, this non-bypassed unit is ideal for pumps, fans, compressors, and conveyors where starting current or water hammer is a constraint. Unlike bypassed models, the MCD 600 maintains SCR conduction during operation, making it suitable for frequent starting duty or installations requiring an external bypass contactor. Key specifications include a control voltage range of 110-240 V AC (separate from motor circuit), IP00 open chassis construction for mounting inside a customer-provided enclosure, and a compact S3 frame size. The unit supports a wide operating voltage range (200-525 V), eliminating the need for voltage-specific variants. With advanced motor and starter protections, the MCD 600 ensures extended uptime and reliability in demanding industrial environments. The MCD 600 is part of Danfoss’s VLT® series, known for flexibility and intelligent features. It includes options for Ethernet/serial communication cards, application-specific smart cards, and multi-language support. The pump clean/reverse function enables bidirectional soft ramps for cleaning applications, while built-in protections safeguard against overloads and faults. For applications requiring variable torque, the MCD 600 delivers consistent performance with minimal thermal stress on the motor. This non-bypassed configuration is optimized for continuous SCR conduction, making it ideal for high-duty-cycle applications. The unit is supplied as an open chassis (IP00) and must be installed in a compatible enclosure to meet environmental protection requirements. Danfoss drives are configured-to-order, with the type code MCD60590CT5S3X00CV2 identifying this exact build. For applications outside the 200-525 V range, consult Danfoss’s WinSTART rating software for alternative configurations.
