Example of 100/(110) VAC

  • The AC100/(110) specification is based on a 100 VAC coil and can be used as follows:

    • AC100V: Can be used for both 50 Hz and 60 Hz
    • AC100V: Can be used for 60 Hz only

  • The AC200/(220) specification is based on a 200 VAC coil and can be used as follows:

    • AC200V: Can be used for both 50 Hz and 60 Hz
    • AC200V: Can be used for 60 Hz only

Signal Relay G6K

Quick tips

  • Relays with lower power consumption tend to have higher maximum allowable voltages.
  • The maximum allowable voltage is the maximum voltage that can be applied to the relay coil, not the continuous allowable value.
