Overview

The internal bypass contactor engages once the motor reaches full speed, allowing the SCRs to carry current only during ramp-up. This design reduces steady-state heat generation and eliminates the need for an external bypass contactor, improving efficiency and reducing enclosure thermal load. Key applications include pumps, fans, compressors, and conveyors where high starting current or water hammer poses operational challenges. The control supply operates independently on 110-240 V AC, requiring verification against panel control voltage during installation. Supplied as an open chassis (IP00), it mounts inside a customer-provided enclosure for protection and cooling. The frame size S2 accommodates the robust internal components, ensuring reliable performance in demanding industrial environments. This soft starter is part of Danfoss's configurable VLT® series, with the exact build identified by type code MCD60410BT5S2X00CV2. Unlike fixed-catalogue drives, Danfoss soft starters are built to order, allowing customization for specific application requirements. The unit's 200-525 V mains compatibility covers the majority of industrial utilization voltages, reducing inventory complexity and simplifying procurement.
  • 410 A continuous current, 200-525 V 3-phase mains compatibility
  • Internally bypassed design reduces SCR heat and eliminates external bypass contactor
  • Control supply: 110-240 V AC (separate from motor circuit)
  • Open chassis (IP00) for mounting in customer-provided enclosure
