Overview

VLT® Soft Starter MCD 500/600 A soft starter for larger motors, available internally bypassed so the SCRs carry current only during the ramp and the unit runs cool once the motor is up to speed. It suits pumps, fans, compressors and conveyors where starting current or water hammer is the constraint and variable running speed is not required. This unit is rated 100 HP, 194 A continuous, frame S2. It is supplied for a 200-525 V mains, so one unit covers the usual utilization voltages in that band rather than requiring a voltage-specific part. The control supply is separate from the motor circuit and runs on 110-240 V — worth checking against the panel's existing control voltage before ordering, because it is a distinct rating from the mains. An internal bypass contactor carries the motor current once the ramp is complete, so the SCRs only conduct during starting. That keeps steady-state heat out of the enclosure and avoids the separate bypass contactor an unbypassed starter needs. Supplied as an open chassis (IP00) for mounting inside a customer enclosure that provides the protection and cooling. Danfoss drives are configured rather than stocked as fixed catalogue items: the type code MCD60194BT5S2X00CV2 identifies this exact build, and 136G8779 is the quick order number Danfoss issues for it. Other valid configurations can be built to order.
