Intermatic MIL72ASWUZH-120 Timer

The Intermatic MIL72ASWUZH-120 is a heavy-duty 7-day electromechanical timer designed for precise HVACR control and commercial automation. Operating at 120V AC, this synchronous drive module features a robust 21A SPDT switch, making it a reliable solution for managing single-phase applications including pumps, motors, and lighting circuits. The unit is built for versatility, supporting both DIN rail mounting and surface installation with its integrated sub-base and terminal cover. For high-demand environments, the captive trippers allow for scheduling in 2-hour intervals, visible through a true clock face for intuitive manual programming. With a high-amperage rating of 21 Amps resistive and a 1 HP motor load capacity at 120V, this industrial time switch ensures consistent performance in temperatures ranging from -40?F to 185?F. The clear plastic dust cover protects the internal screw terminal connections, which accommodate up to #12 AWG wire, ensuring a secure and professional installation in any control panel.

Key Benefits:

• Universal Mounting: Designed for seamless integration with surface mount or DIN rail configurations in standard control panels.
• High Load Capacity: Equipped with a 21A SPDT relay capable of handling 1 HP motor loads and 1350W tungsten loads.
• Precision Scheduling: Features a 7-day program dial with non-removable captive trippers to prevent lost parts and ensure schedule integrity.
• Manual Override: Includes a three-way OFF/AUTO/ON override switch for immediate manual control without disrupting the programmed cycle.
• Industrial Durability: Housed in a rugged plastic enclosure with a clear dust cover, rated for extreme commercial refrigeration and boiler environments.

Common Questions:

Does this model include a battery backup for power outages?
No, the MIL72ASWUZH-120 is a synchronous drive model that relies on the line frequency for timing accuracy and does not include a quartz battery backup.

What is the minimum switching interval for this 7-day timer?
The minimum ON/OFF time for this module is 2 hours, defined by the physical spacing of the captive trippers on the 7-day dial.

Can I use this to control a 240V motor?
This specific model is rated for a 120V AC input. While the SPDT contacts can technicality switch higher voltages, the clock motor itself requires a 120V supply to function.
