Time switch Hager EGK103

The Hager EGK103 is a wired time switch designed for controlling single-phase AC motors and other resistive or inductive loads. It accepts an AC input voltage of 230 V at 50–60 Hz and provides a switching capacity suitable for small motors and general electrical loads with a rated current of 16 A. The device enables scheduled on/off operation to reduce unnecessary running time, improve energy efficiency, and provide predictable automation for building services and equipment control.

Advantages

The time switch features robust electrical contacts rated for 16 A, compatible with common single-phase installations. Its wired design ensures a stable connection for continuous operation and reliable timing performance. The unit is built to integrate into existing control circuits, offering precise timed switching without dependence on wireless signals or external control systems. Installation and configuration focus on straightforward wired connectivity and clear operational behavior.

Suitable for (tasks / use cases)

• Controlling single-phase AC motors such as small ventilation fans or pump motors
• Scheduled switching of lighting circuits or heating elements
• Automated control for building services and equipment maintenance routines
• Reducing energy consumption by limiting run times of non-continuous loads

Key specifications

• Supply voltage: 230 V AC
• Frequency: 50–60 Hz
• Rated switching current: 16 A
• Designed for single-phase AC loads
• Wired connection type suitable for fixed installations

How to use

Mount the time switch in accordance with local electrical codes and the manufacturer's wiring guidelines, ensuring power is isolated before connection. Connect the supply and load conductors to the appropriate terminals for single-phase operation and configure timing settings as required for the application. After wiring, restore power and verify correct switching behavior by testing scheduled on/off cycles under no-load and then normal-load conditions. Adjust timing as needed to match operational requirements.

Usage recommendations

Ensure the connected motor or load does not exceed the 16 A rated current and consider inrush currents for inductive devices. Use appropriate overload protection and contactors when controlling larger motors or loads with high starting currents. Periodically inspect wiring terminals for secure connections and verify timing accuracy as part of routine maintenance.
