Intermatic MIL72ASTUZH-240 Timer

The Intermatic MIL72ASTUZH-240 is a heavy-duty 24-hour electromechanical timer designed for precise automated control in light commercial and industrial HVACR environments. Operating at 240V AC, this SPDT time switch is engineered with a high-torque synchronous drive that maintains timing accuracy for critical systems. The unit distinguishes itself with captive trippers at 15-minute intervals, providing up to 48 programs daily with no loose parts to misplace during field adjustments. Whether you are managing refrigeration defrost cycles, pump sequences, or commercial lighting, the 21A resistive rating and 2 HP motor capacity ensure reliable switching under significant inductive loads. The universal mounting design supports both DIN rail and surface mount configurations, making it a versatile drop-in replacement or new installation component for standard control panels.

• Multi-Mount Versatility: Dual-purpose base allows for rapid DIN rail mounting or stable surface installation with a simplified terminal layout.
• Field-Proven Reliability: The robust electromechanical mechanism withstands wide temperature fluctuations, operating efficiently from -40°F to 185°F.
• Manual Override Switch: Includes a three-way manual override (ON/OFF/AUTO) to simplify maintenance and system testing without disrupting the programmed schedule.
• Clear Protective Cover: Features a transparent, dust-resistant housing that protects the real-time clock face while allowing instant visual verification of the current settings.
• High Load Capacity: Rated for up to 21 Amps and 2 HP at 250 VAC, making it compatible with heavy HVAC fans, blowers, and compressor contactors.

• Can this timer be used for 208V applications? Yes, the MIL72ASTUZH-240 is rated for 208-240 VAC single-phase circuits, making it ideal for standard commercial motors and lighting.
• What is the minimum switching interval? The captive trippers allow for a 15-minute minimum ON/OFF time, providing 96 total tripper positions for a highly granular 24-hour schedule.
• Does this model include battery backup? No, this is a synchronous drive model. For applications requiring power-loss carryover, a quartz-driven "Q" series model would be required.
