240 VAC Switch
—A 240VAC, 50 Hz power supply is needed to remotely reset
the switch by energizing a solenoid. Upon applying 240VAC to the solenoid,
the unit will need 92mA to energize the remote reset coil. At standard ambient
temperature, the solenoid has a 25% “on” 75% “off” cycle.
Maximum allowed On Time (remote reset energized) versus minimum
Off Time (remote reset de-energized).

A power ON delay may be required when starting tower fan motor across
the line (DOL). A 15 second delay is suggested to allow the fan to come
up to full speed before allowing the switch to activate.
