Specification
The time switch shall be a 7-Day dial type that will provide a photo control to turn loads ON/OFF. The time switch shall
turn loads ON/OFF for ____________(2 Circuits)(3 Circuits) on a 7-Day schedule. The time switch shall be powered by
a 125 VAC, 60 Hz power supply. The time switch shall have a synchronous motor designed to withstand a minimum of
6000 volt transients. The time switch motor shall be connected to the terminal strip with ring-type connectors and shall
not require more than 5 watts to operate. The time switch mechanism shall be mounted in a Type 1 lockable steel
enclosure painted with an electrostatic process to eliminate the potential for corrosion. The enclosure shall provide a
non-removable cover, which shall swing open a full 180 degrees. The time switch shall provide a manual override for
each circuit. The time switch shall provide separate terminals for clock motor for switching circuits not on line voltage.
The time switch shall be designed to operate mechanically held contactors and shall have a switch rating of:
• 15 Amp, ½ HP, 125/250 VAC
• 420 VA Pilot Dut
• 150 Watts Tungsten, 125 VAC
The time switch shall contain a spring-wound carryover and shall maintain time control on schedule during power failure
for up to 16 hours. The carryover shall automatically rewind upon power resumption. The time switch shall also provide a
terminal for connection of a 150 Watt load for direct photo control. The photo control shall have a light level adjustment
and shall be sonically welded in weatherproof polymeric housing. The time switch shall have independent clock
terminals, which may also be used with 24 Volt systems if wired in accordance with National Electrical Code regulations.
The time switch shall be agency listed under Clock Operated Switches and shall be Intermatic model _____________(See
Model Numbers Listed).
