Renle new Model: RNMV 3.3KV / 6KV/ 11KV/ 24KV 0-1300A SOFT STARTER 

→ Features of SOFT STARTER series medium voltage soft starter 
→ The operation interface with switchable Chinese/English languages is easy to learn. 
→ The trigger circuit with isolated fiber ensures the full isolation between high and low 
voltage. 
→  Several  groups  of  SCR  in  series  are  connected  into  the  high-voltage  control 
components,  each  component  comes  with  the  equalizing  circuit  and  real-time  voltage 
protection circuit. 
→ Comprehensive and flexible motor protections for overload, over current, undervoltage, 
open-phase, stall rotation, etc. Which can be turned on and off separately with settable 
protected level. 
→ To ensure complete equipment protection for medium voltage soft starter, SCR over 
current, over temperature, power supply open phase protection, excessively long starting 
time protection and the setting of time interval between starts. 
→ The phase angle dynamic tracking feedback components to ensure that any load starts 
successfully. 
→ Modbus/Profibus is selectable for Field bus. 
→ 0-20mA/4-20mA programmable output. 
→ Programmable input/output can be used flexibly. 
→ Multiple sets of start parameters to meet different load use.

1.2 Design Structure 
medium  voltage  (3300V—15000V)  soft  starter  should  be  used  together  with  inlet 
cabinet equipped with disconnector switch. 
 
→ Load Switch: 
The load switch on the inlet cabinet allows the motor with the load to start. This switch 
has the ability to start with on-load short-circuit and stop when load stop. Its maximum 
design  value  is:  5KV  load  switch  is  for  2300V-4160V  starters,  7.2KV  is  for 
6000V-7200V starters, while 15KV is for 10KV-14KV soft starting cabinet. 
 
→ Soft Starting Cabinet: 
The  soft  start  section  is  composed  of  bypass  vacuum  contactor,  SCR  overvoltage 
protection, SCR high-voltage components, RC absorption network, trigger circuit and 
control components.  
→ Bypass Vacuum Contactor 
The contactor is closed after the soft starter starts the motor, the current through the 
bypass  vacuum  contactor.  The  selected  voltage  ratio  of  the  contactor  is:  5KV  for 
2300V—4160V; 7.2KV for 6000V-7200V, and 15KV for 10KV-15KV soft starters. 
 
→ RC Absorption Circuit 
To provide transient voltage protection circuit to reduce the dv/dt impulse voltage thus 
avoiding damage to thyristor. 
 
→ Trigger Circuit 
To  provide  high-power  trigger  pulse  of  up  to  more  than  2A  to  ensure  the  dynamic 
voltage balance of SCR connected in series. Both trigger circuit and SCR are at high 
voltage and separated from control panel through fiber and transformer. 
 
→ SCR high Voltage Components 
This consists of several SCR connected into series, see table 1.1 below
