Intermatic E1020 Time Switch

The Intermatic E1020 is a rugged, heavy-duty 24-hour mechanical time switch engineered for high-demand HVAC and electrical loads. Designed for professional-grade reliability, this 120V 15A SPST timer is the industry standard for automating ventilation fans, circulator pumps, and industrial lighting circuits. Unlike basic residential timers, the E1020 supports multiple ON/OFF cycles (up to 12 per day) using removable trippers, allowing for precise 30-minute interval adjustments to meet complex operational schedules. This in-wall mechanical timer fits into any standard single-gang junction box, making it a direct replacement for manual switches when energy efficiency and automated load management are required. With a 1800-watt resistive capacity and a 12 FLA motor rating, it handles inductive surges from HVAC blowers without premature contact wear. The visible 24-hour dial and manual override lever provide field technicians with immediate diagnostic feedback and the ability to bypass the schedule for maintenance without losing the timer switch settings.

• High Load Capacity: Rated for 15 Amps at 120 VAC, making it suitable for heavy-duty motor and tungsten loads.
• Flexible Scheduling: Provides up to 12 ON/OFF operations per day with minimum 30-minute intervals for superior control.
• Simplified Installation: Standard in-wall mounting design fits most single-gang electrical boxes for fast retrofits.
• Reliable Mechanism: Robust mechanical 24-hour timer dial ensures schedule retention regardless of complex programming.
• Manual Override: Integrated toggle allows for instant manual activation without affecting the daily program.

Does this unit require a neutral wire for installation?
Yes, the Intermatic E1020 utilizes a synchronous motor and requires a neutral connection (three-wire setup) in the junction box to function.

Can I use this timer for a 240V pool pump or heater?
No, this model is rated specifically for 120V AC 60 Hz applications. For 240V circuits, a DPST or appropriate double-pole model is required.

How many trippers are included with the E1020?
The unit typically ships with two pairs of ON/OFF trippers. Additional trippers (part number 156EB1945A) can be added to achieve the maximum 12-cycle limit.
