Why Choose the ABB AW1CO-R-120m Mechanical Time Switch?
The ABB AW1CO-R-120m is an electromechanical weekly time switch designed to automatically control electrical loads according to a repeating seven-day programme. With one switching channel and straightforward analogue programming, it provides dependable scheduled control for lighting, heating, ventilation and other electrical equipment.
The AW1CO-R-120m uses an 84-pin weekly programming dial with a minimum switching interval of 120 minutes. A three-position manual selector provides permanent OFF, automatic and permanent ON operation, allowing the connected circuit to be overridden whenever required.
Operating from a 230 V AC, 50/60 Hz supply, the time switch offers a 16(4) A at 250 V AC switching capacity and a 150-hour power reserve. Its compact 2.5-module DIN-rail enclosure makes it well suited to distribution boards and control panels requiring reliable weekly scheduling.

Reliable Weekly Automatic Load Control
Weekly time switches automatically operate electrical circuits according to schedules that repeat every seven days. The ABB AW1CO-R-120m uses a mechanical programming dial to provide straightforward scheduling without requiring digital menus or external programming equipment, making routine setup and adjustment simple.
The integrated 150-hour running reserve helps maintain timing during temporary mains interruptions, while the three-position manual selector allows the connected circuit to remain permanently disconnected, follow the programmed schedule or remain permanently connected. This combination provides practical flexibility for everyday building-services and electrical-control applications.
Typical Applications
- Commercial and public-building lighting schedules.
- Heating and ventilation equipment.
- Shop and display lighting control.
- Irrigation and watering systems.
- Residential electrical load scheduling.
- Weekly control of pumps, signs and other electrical equipment.
