Note *1: The ambient temperature is the temperature near the product during operation.
Note *2: If Magnetic Starters are used in combination with Thermal Overload Relays and the products are used with continuous through current without providing
gaps, temperature increases will reduce the life of the coil.Also, the characteristics of the Thermal Overload Relays will vary somewhat from the mutual
thermal effects between the heaters.When using the products under these conditions, separate the products from each other by at least 5 mm (dimension A).

Rail Mounting
The SK06 to SK12 Magnetic Motors and
Starters can be mounted to 35mm-wide
support rails. Secure the rail with the
mounting pitch that is shown in the figure
at the right.
Example of Applicable Rail: TH35-15AL
Voltage Fluctuation Range in Control Circuits and Voltage Drop
SK06 to SK12A (AC Operation)
Drop-out voltage (operating voltage): 85% to 110% of rated voltage
However, there is an official rated inrush voltage, but usage is possible
without contact welding even if the voltage drops to 75% of the rating
when the main contacts close.
SK06 to SK12G, L-shape Drop (DC Operation)
Drop-out voltage (operating voltage): 85% to 110% of rated voltage
at ambient temperature of 55°C and 80% to 110% of rated voltage at
ambient temperature of 40°C.
However, there is an official rated inrush voltage, but usage is possible
without contact welding even if the voltage drops to 75% of the rating
when the main contacts close.
