Overview
Standards
IEC 60947-1, EN 60947-1,
IEC 60947-4-1, EN 60947-4-1,
IEC 60947-5-1, EN 60947-5-1 (auxiliary switches)
The contactors are suitable for use in any climate.
They are finger-safe according to IEC 60529.
The contactors are suitable for switching mixed loads in
distribution systems (e.g. for supplying heaters, lamps, motors,
PC power supply units) with p.f. > 0.8 according to
IEC 60947-4-1 test conditions for utilization category AC-1.
