1.5 Certifications
1.5.1 European EMC Directive
If the SK 1x5E is installed according to the recommendations in this manual,
it meets all EMC directive requirements, as per the EMC product standard
for semiconductor motor control devices EN 60947-4. (see also Section 7.3,
Electromagnetic Compatibility [EMC].)
1.5.2 UL and cUL approval (in preparation)
At present the approvals are in the process of preparation.
All SK 1x5E motor starters include motor overload protection. Further technical details can be found in
Section 7.2.
NOTE
"Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electric Code and any
additional local codes."
NOTE
“The device has to be mounted according to the manufacturer instructions.”
"Use 80°C Copper Conductors Only"
