Introduction:
- Lorentzzi® SUL180 is a popular compact DIN rail-mounted 24-hour mechanical timer switch, offering advantages such as easy installation and convenient time setting.
- Its housing dimension is 17.9*60*90 mm(L*W*H). If you compare it with a 1P miniature circuit breaker, their dimensions are nearly the same. Therefore, we can fix many pieces of this 24 hour mechanical timer onto a din rail rack very easily.

- Its minimum setting time range is 15 minutes, maximum setting time is 24 hours, so it is a 24 hour timer switch.
- Maximum output current is 16 A, thus, it can run a 2000 W@220 VAC resistive load without problem. But if you want to run a heavier load, using an AC contactor or AC/AC SSR is a good choice.
- Additionally, there is a backup battery inside this 24 hours mechanical timer switch, it can ensure this timer can work 72 hours once power fails.
- Applications include billboard time switches, geyser time switches, irrigation, street light control, swimming pool distribution boxes, etc.

How To Set This Mechanical Timer?
- Set Running Time: Move the dial (encoder wheel) to the right (off) or left (on) to set the duration of the on/off state.
- Adjust Current Time: After completing the first step, the next step is to set the current time. For example, if the current time is 12:15, the dial should be moved to that position.
- Set Working Mode: Two modes are available. The top one is “Automatic” mode, where the timer will automatically turn on/off according to your set time. The bottom one is non-timed mode, where the timer will not run.
