Spark Quenching Unit Type 070.000.6
Application
Reduces spark production on the switching contacts occurring during VDC inductive load switching.
• Voltage limitation according to VDE0580 2000-07, Item 4.6.
• Reduction of EMC-disturbance by voltage rise limitation, suppression of switching sparks.
• Reduction of brake engagement times by a factor of 2-4 compared to free-wheeling diodes.
E189728 V V
Function
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.
