Do the U-Line starters have integrated suppression? What type of suppressor do we use?
Issue:
Identify if the U line has an integrated suppressor module.
Product Line:
TeSys U IEC Starters
Environment:
IEC Contactors and Starters
Resolution:
U-Line starters have integrated suppression. The LUC's A1 & A2 terminals are connected to a high power carbon resistor (used as current/voltage damper) connected in series with a varistor limiting electronic circuit control voltage available at its terminals. Capacitors (to cope with circuit current demand) are connected in parallel with the varistor. The coil itself has a diode + Zener diode to limit the voltage on de-energization to around 24v. No additional suppression is required.
