Intermatic MIL72ASTUZH-24 Timer

The Intermatic MIL72ASTUZH-24 is a professional-grade 24V electromechanical timer designed for high-reliability switching in commercial HVACR and light industrial control panels. Featuring a 24-hour cycle with captive trippers at 15-minute intervals, this module allows for precise scheduling of 24 VAC single-phase circuits. The SPDT switch is rated for 21 Amps resistive and up to 2 HP at 250 VAC, making it an ideal choice for refrigeration merchandisers, ventilation fans, and motor control. This unit supports versatile surface or DIN rail mounting, with a synchronous drive that ensures timing accuracy based on line frequency. The clear plastic dust cover protects the true clock face, which includes hour and minute hands for intuitive setting and monitoring. With an integrated manual override switch (OFF/AUTO/ON), technicians can bypass programmed schedules without losing setpoints, providing flexibility during system maintenance or field testing. Its wide operating temperature range of -40?F to 185?F ensures consistent performance in demanding mechanical rooms.

• Universal Mounting Flexibility: Supports both DIN rail and surface mounting, allowing for seamless integration into existing control cabinets or as a standalone component.
• High Amperage Capacity: The 21A SPDT switch handles demanding inductive and motor loads, supporting up to 2 HP at higher voltages.
• Maintenance-Free Programming: Captive trippers cannot be lost and provide 48 distinct ON/OFF programs per 24-hour period.
• System Reliability: The synchronous motor drive provides long-term timing stability for HVACR and lighting automation.
• On-Site Control: A three-way manual override allows immediate status changes without disrupting the master schedule.

• Can this timer be used for DC applications? While the synchronous motor is designed for 24 VAC, the SPDT dry contacts can switch various loads, but always verify current ratings against your specific DC requirements.
• Does this model have a battery backup? No, the MIL72ASTUZH-24 is a synchronous model; for applications requiring power-loss carryover, look for the 'Q' quartz-driven models.
• How do I set the program? Simply push the captive trippers outward for 'ON' periods and inward for 'OFF' periods. Use the central clockwise minute hand to set the current time of day.
