Intermatic MIL72ASTUZ-240 Timer

The Intermatic MIL72ASTUZ-240 is a heavy-duty 24-hour electromechanical timer module engineered for precise control in light-duty commercial and industrial environments. This 240V surface/DIN rail mount switch is a preferred choice for contractors managing HVACR systems, lighting circuits, and motor-driven applications like pumps or fans. Featuring a high-capacity 21A SPDT switch, it provides reliable 1-pole changeover performance with a 2 HP rating at 250 VAC. The synchronous drive mechanism ensures timing accuracy across a wide operating temperature range of -40°F to 185°F, making it suitable for unconditioned mechanical rooms. The unit is designed for versatile installation, accommodating both DIN rail mounting or surface mounting within a control panel. Captive trippers allow for program intervals as short as 15 minutes, while the integrated clear plastic dust cover protects the true clock face from debris. This model is ideal for fixed-schedule energy management and generator exercising where a battery backup is not required.

• Universal Mounting: Fits standard 35mm DIN rail or can be surface mounted, providing flexibility for panel retrofits and new builds.
• High Current Handling: The 21-amp resistive rating allows for direct control of larger loads without the immediate need for an external contactor in many light commercial applications.
• Simplified Programming: Captive trippers eliminate the risk of lost components, allowing for quick 15-minute interval adjustments on the 24-hour dial.
• Environmental Resilience: Engineered to withstand extreme temperatures, ensuring the synchronous drive remains accurate in varied climates.
• Heavy-Duty Termination: 12 AWG screw terminals ensure secure, vibration-resistant electrical connections for long-term field reliability.

• Does this model include a battery backup for power outages? No, the MIL72ASTUZ-240 is a synchronous drive model. For applications requiring a 72-hour carry-over, the "Q" version with a quartz drive should be specified.
• Can I use this timer for 120V applications? This specific module is rated for 208/240 VAC. Using it on a 120V circuit will result in improper timing or failure of the drive motor.
• Is the manual override switch included? This module features a 3-way override (ON/AUTO/OFF) to allow technicians to test loads or bypass the schedule during maintenance without losing the programmed settings.
