Analog Time Switch Eti-Polam APC-DR1 1P 16A 230V AC daily 100h

Eti-Polam APC-DR1 analog time switch is a single-pole (1P) mechanical programmer designed for 230 V AC mains installations. Rated for 16 A switching current and configured for daily 24-hour cycles, this device allows timed control of lighting, electric heaters, ventilation, pumps and other loads in residential and light commercial settings. The unit provides a simple, manually settable dial and a 100-hour setting/backup range to maintain scheduled operation after temporary power interruptions or during manual adjustments.

Advantages

The mechanical design of the Eti-Polam APC-DR1 offers straightforward, reliable operation without the need for software or network connectivity. Its compact single-pole construction makes it suitable for DIN-rail or panel mounting where a single switched phase is required. The 16 A rating covers most household and small commercial loads, while the daily 24-hour cycle and 100-hour setting range give practical flexibility for routine scheduling and temporary overrides.

Suitable for

• Timed control of indoor and outdoor lighting circuits
• Switching electric heaters, convectors or towel rails on a daily schedule
• Controlling ventilation fans and extractors for scheduled operation
• Operating small pumps or water heaters with daily cycles
• Basic automation tasks in apartments, houses and small shops

When it may not be suitable

This analog time switch is not intended for multi-pole three-phase installations or for loads that require switching currents above 16 A. It does not provide digital programming, remote control or integration with smart-home systems, so it may not meet requirements where networked scheduling, complex weekly programs or app control are needed.

Key specifications

• Supply voltage: 230 V AC
• Contact configuration: single pole (1P)
• Switching capacity: 16 A
• Operating cycle: daily (24 h)
• Mechanical setting: analog dial with manual segments
• Setting/backup range: 100-hour range for adjustments and temporary power interruptions

How to use

Mount the time switch in the electrical panel or on DIN-rail according to installation rules and local wiring regulations. Connect the phase conductor to the input terminal and the switched output to the load, ensuring proper earthing for the installation. Set the current time on the dial and place the on/off segments or pins for the required daily switching intervals. Verify operation by stepping the dial through one full rotation and observing the output state. For safety, isolate mains power before wiring and consult a qualified electrician if unsure.

What to consider before purchase

• Ensure the 16 A switching capacity is adequate for the intended load and consider inrush currents for motors or heaters
• Confirm single-pole switching is suitable for your installation; multi-phase loads require different devices
• Decide if mechanical daily programming meets your scheduling needs or if digital/remote options are required
• Check physical mounting space and compatibility with your electrical panel or DIN-rail layout

Usage recommendations

For reliable long-term operation, place the switch in a dry, temperature-stable enclosure and avoid exposing it to excessive dust or vibration. Use the 100-hour range feature to maintain settings during short power outages and perform a monthly check to confirm the programmed intervals match actual needs.
