  1. VLT Soft Start Controller MCD 100

  2. Soft Start Market Segmentation Schneider LH4N1 The Soft start market is currently divided into five segments. Medium voltage Torque Limiters Siemens Sirius Digital Soft Starters Schneider Altistart48 Soft Start Controllers Compact Soft Starters MCD3000 Schneider ATS01 MCD202

  3. MCD 100 Soft Start Controller Soft Start Controllers provide Timed Voltage Ramp up and down. Motor protection must be installed separately. MCD 100 Soft Start Controller 0,1 – 11kW MCD 201 Soft Start Controller 7,5 – 110kW

  4. The Range 3 Frame Sizes1.5 kW ~ 11 kW @ 400VAC Line Voltage 208 ~ 600 VAC Universal control voltage 24 – 480 VAC/VDC ProtectionIP20 ApprovalsCEUL CSA

  5. Unique design • Robust SCR design • Selection based on power - simplifies selection • No derating • Unlimited number of starts • Heavy ratings as standard • Contactor style design • Easy selection • Simple and straight forward installation and commissioning • Little panel space required • Universal control voltage • 24 – 480 VAC/VDC • Easy selection - few part numbers • Digitally controlled rotary switches • Precise and safe adjustments

  6. MCD 100-001 22 mm module Rated 1.5 kW @ 400V Rating index AC 53b: 3A: 5-5:10 Power loss Max. 4W (internal bypass) Universal control voltage 24 – 480 VAC/VDC Ramp times 0 – 10 seconds

  7. MCD 100-007 45 mm module Rated 7.5 kW @ 400V Rating index AC 53a: 15A: 8-3:100-3000 Power loss 2 W/A x duty cycle Universal control voltage 24 – 480 VAC/VDC Ramp times 0 – 10 seconds

  8. MCD 100-011 90 mm module Rated 11 kW @ 400V Rating index AC 53a: 25A: 8-3:100-3000 Power loss 2 W/A x duty cycle Universal control voltage 24 – 480 VAC/VDC Ramp times 0 – 10 seconds

  9. Indication Two LED Indicators are provided on MCD 100 soft starters: • Stand by • On Each LED can be off, on or flashing. LED 1 LED 2 Stand by Starting Full on Stopping Line or load error

  10. Example 1 Example 2 Application MCD 100 can be installed with our without a line contactor. Motor overload protection must be mounted seperately (overload relay or circuit breaker). Short circuit protection can be obtained with fuses or circuit breaker. Use semiconductor fuses to protect the soft starter. • MCD 100 • Soft start/stop • Circuit Breaker • Overload protection • Short circuit protection • Line contactor • Start/stop and isolation • MCD 100 • Line controlled soft • start/stop • Circuit Breaker • Overload protection • Short circuit protection
