Time based control of lighting, ventilating, heating, cooling or other electrical loads in commercial and industrial applications. The MIL 72 time switches come with a 24-hour dial with a SPDT switch (form "C" contact). The MIL 72A series is intended for surface mounting. The control is completely enclosed in a plastic housing and includes a terminal cover and sub-base for installation and hard wiring.
. Synchronous drive or quartz drive with battery backup
. 21A SPDT switch
. Captive trippers with interval as low as 15 minutes
. With or without 3-way override
. Real clock face
. Surface, flush, or DIN rail mount

Furnish and install a Grasslin MIL 72____ 24 hour (7 day) time switch with 15
min. (2 hour) interval captive trippers and quartz (synchronous) drive. Input
voltage shall be 120V (24V, 240V, 277V) and SPDT switch contacts shall be
silver cadmium oxide rated at 21A, resistive, 2HP @ 250VAC. To set the starting
time and to provide time indication, the unit shall incorporate an authentic
clock face. Installation for surface, (flush, DIN rail or within indoor or outdoor enclosure) mounting. Time switch shall contain an OFF/AUTO/ON override.
For Carry-over: The time controls shall have a quartz drive with 7 day reserve
carry-over from a rechargeable battery.
