Suitable for

• Residential apartment building staircases
• Commercial office hallways
• Basement and utility room lighting control
• Common areas in multi-family housing

This device may not be suitable for high-power industrial machinery or heavy-duty motor applications that exceed the 16A current rating. It is also not designed for outdoor environments without an appropriate weather-resistant enclosure, as it requires protection from moisture and extreme temperatures.

Key specifications

• Operating voltage: 230V AC
• Maximum current: 16A
• Time delay range: 20 seconds to 10 minutes
• Contact configuration: 1NO (Normally Open)

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is typically mounted on a standard DIN rail within a distribution board. Once installed, the desired time delay is set using the adjustment dial on the front of the unit. When the connected push-button is pressed, the timer activates the lighting circuit for the pre-set duration before automatically switching it off.

What to consider before purchase

• Verify that the total load of the connected lighting fixtures does not exceed the 16A limit.
• Ensure the installation location has sufficient space within the electrical distribution panel.
• Confirm compatibility with existing push-button wiring configurations.

For optimal performance and longevity, ensure that the timer is installed in a dry, dust-free environment and that all terminal connections are tightened securely to prevent overheating.
