Overview

The Danfoss VLT® Soft Starter MCD 600 (SKU: 136Z4337) is a high-capacity, non-bypassed soft starter designed for fixed-speed motor applications up to 600 HP (839 A continuous). It supports a wide input voltage range of 380-690 V, eliminating the need for voltage-specific configurations. The control supply operates independently on 110-240 V AC or 24 V DC, ensuring compatibility with existing control systems. This unit is supplied as an open chassis (IP00) for integration into customer-provided enclosures, offering flexibility in mounting and cooling solutions. Key applications include pumps, fans, compressors, and conveyors where high starting currents or water hammer are concerns. The non-bypassed design ensures SCRs remain active during motor operation, making it ideal for frequent starting duty or installations requiring external bypass contactors. The MCD 600 features advanced motor and starter protections to maximize uptime, along with support for multiple communication protocols via optional cards. Frame S3 construction accommodates a current range of 144-579 A in IP00 configuration, with additional enclosure options (IP20, IP21, IP54, IP55, IP66) available for enhanced protection. The unit is configurable rather than stocked, with the type code MCD60839CT7S3X00CV2 specifying this exact build. For OEMs and system integrators, the MCD 600 provides a reliable, modular solution tailored to industrial automation needs.
