Note: 1. The above timing ranges apply when the internal variable resistor of H3FA is used.
2. The external variable resistor may also be used by opening the terminal connected to the internal variable
resistor.
3. Wire the appropriate terminal to select a time setting range. Refer to Rated Time and Terminal Connections on
Data Sheet for details.
