SKKQ 1200/18E
Preliminary Data
Features
• Compact design
• Thyristor with amplifying gate
• Pressure contact technology
Typical Applications*
• Soft starters
Remarks
• Please note: This module has no soft
mold protection around the chip. It is
therefore susceptible to environmental
influences (dust, humidity, etc.). The
humidity test according to
IEC60068-2-67 is not passed by this
product.
• Recommendation: The devices should
be installed in control cabinets of IP54
degree of protection.
