Couldn't load pickup availability
The ABB AD1CO-R-15m (2CSM208151R1000) is a daily analogue time switch for DIN-rail distribution boards. Push the captive segments on the 24-hour dial to set exactly when a load turns on and off, in 15-minute steps, and the switch repeats the programme every day automatically.
Its changeover (CO) contact switches up to 16 A resistive load directly, or drives the coil of a modular contactor for bigger loads. A built-in power reserve keeps the clock running during power cuts, so you do not need to reset the time after every outage.

Frequently asked questions
How do I program the ABB AD1CO-R-15m?
Set the dial to the current time, then push down the segments for every 15-minute period you want the load ON. Put the selector on automatic and the programme repeats every day.
Can it switch a water heater or a big load directly?
It can switch up to 16 A resistive load directly. For bigger loads, motors or three-phase circuits, use it to control the coil of a modular contactor such as the ABB ESB range.
What happens during a power cut?
The built-in power reserve keeps the clock running, so the programme stays in time once the power comes back.
What does CO mean?
CO is a changeover contact (1NO + 1NC): one side closes when the programme is ON, the other when it is OFF.
