MCD 200 Series Overview
■ MCD 200 Series Overview
■ Description
The Danfoss MCD 200 Soft Starter series comprises
two separate ranges:
• MCD 201
• MCD 202
MCD 201 and MCD 202 soft starters share a common
power and mechanical design, but offer different levels
of functionality.
MCD 201 soft starters provide TVR (Timed Voltage
Ramp) starting and stopping control and are designed
for use with an external motor protection device.
MCD 202 soft starters provide Current Limit starting
control, TVR soft stop and include a range of motor
protection functions.
NB!:
This manual makes reference to MCD 200,
MCD 201 and MCD 202. The MCD 200
designation is used when referring to characteristics
common to both the MCD 201 and MCD 202 ranges.
In all other cases the text refers to the specific range
MCD 201 or MCD 202.
MCD 200 soft starters include an integral bypass
function that bypasses the soft starter SCRs during
run. This minimises heat dissipation during run and
makes the MCD 200 suitable for installation within
non-ventilated enclosures without the need for an
external bypass contactor.
