Specifications Time Ranges Model Rated time Time setting range H3FA-A 1 s 0.1 to 1 s H3FA-AU 10 s 1 to 10 s H3FA-SA 1 min 0.1 to 1 min H3FA-SAU 10 min 1 to 10 min H3FA-B 6 s 0.6 to 6 s H3FA-BU 60 s 6 to 60 s H3FA-SB 6 min 0.6 to 6 min H3FA-SBU 60 min 6 to 60 min 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 page 4 for details. 2
