Product Description:

The model MCD202015T4CV3 is an advanced soft starter designed for precise motor starting control. It is equipped with current limit and soft stop features to ensure smooth operation. The unit integrates various motor protection functions and is ideal for installations requiring compact design and heat efficiency.

This MCD202015T4CV3 Soft Starter from Danfoss supports Current Limit starting control which allows adjustment from 250 % to 475 % of Full Load Current (FLC). The default setting is 350 % that enables the motor to accelerate effectively while preventing overcurrent. The soft starter also includes TVR (Timed Voltage Ramp) soft stop functionality that is adjustable between 2 to 20 seconds or can be disabled if needed. The control inputs of this model include Start Terminal N1 which is Normally Open and Stop Terminal N2 which is Normally Closed, each rated for up to 300 VAC maximum. The excess Start Time Protection is configurable from 2 to 20 seconds with a default value of 10 seconds. This prevents prolonged start attempts that can damage the motor. It supports EMC immunity parameters including 4 kV contact discharge and 8 kV air discharge for electrostatic immunity. The rated impulse withstand voltage is 2 kV (fast transient 5/50 ns) and it tolerates electromagnetic interference across 0.15 MHz to 1000 MHz with 140 dB (μV) protection. This soft starter is optimized for user flexibility and operational safety. The built-in motor protection suite includes start time monitoring and current limiting to prevent excessive electrical stress.

The MCD202015T4CV3 Soft Starter features an integral bypass function that automatically bypasses the internal SCRs once the motor reaches full speed. This significantly reduces heat dissipation and improves efficiency during continuous operation. This feature also allows for installation in non ventilated enclosures. Its design minimizes component stress during start and stop operations.
