Spark quenching unit

Spark quenching unit:

  • Reduces EMC disruption
  • Reduces spark production on the contacts

Reduces spark production on the switching contacts occurring during DC-side switch-off of inductive loads 

  • Voltage limitation according to VDE 0580 2000-07, Item 4.6
  • Reduction of EMC disruption by voltage rise limitation, suppression of switching flanks
  • Reduction of brake engagement times by a factor of 2 - 4 compared to freewheeling diodes 

The spark quenching unit will absorb voltage peaks resulting from inductive load switching, which can cause damage to insulation and contacts. It limits these to 70 V and reduces the contact load. Switching products with a contact opening distance of > 3 mm are suitable for this purpose.
