  • Note 1: The table above indicates the guideline values of characteristics when using a 200 V AC coil during AC operation (B-N□), and when using 100 V DC during DC operation (BD-N□).
  • Note 2: Operating voltage is 20°C cold state, for both AC operation (at 60 Hz) and DC operation. For coils other than 200 V AC and 100 V DC, purchase approximately proportional to the voltage.
  • Note 3: Input and power consumption are shown as average values. Stays nearly the same even when using coils other than 200 V AC or 100 V DC.
  • Note 4: Coil current is the average value when applying 220 V 60 Hz during AC operation, and when applying 100 V DC. When using a coil other than the 200 V AC coil, divide the constant input by the coil voltage to find the coil. When using a coil other than the 100 V DC coil, divide the power consumption by the coil voltage.
  • Note 5: Operating time is the value when applying 220 V 60 Hz during AC operation, and 100 V DC during DC operation. Stays nearly the same even when using coils other than 200 V AC or 100 V DC.
