Earth leakage indicator NEF30WU 24V-230V green W0-NEF30WU Z

Earth connection indicator – reliable safety signaling

This earth connection indicator from the NEF30 series is a simple yet crucial device that informs about the correct grounding of the circuit. Its task is to signal the grounding status, giving confidence that the electrical installation is operating safely. Installing the indicator is a quick way to visually check the grounding status, which is particularly important in industrial systems, but also useful in building installations.

Construction and application

The indicator uses LEDs to signal the grounding status. This ensures low energy consumption and high device durability. The LED-based design provides long life and reliable operation. Indicators from the NEF30 series are universal and can operate in a wide range of voltages – from 24V to 230V AC/DC, making them ideal for various applications. The metal housing and polycarbonate cover guarantee resistance to mechanical damage and harsh industrial conditions.

The indicator finds application everywhere where monitoring the grounding status is necessary:

• in industrial automation and power systems,
• in synoptic panels,
• in electrical installations of buildings.

Key features and benefits

• Grounding status signaling: immediate information about correct or incorrect grounding of the circuit.
• Wide voltage range: ability to work in both direct current (DC) and alternating current (AC) circuits – 24-230V.
• Durability and reliability: LEDs ensure long life and stable operation.
• Resistance to external conditions: metal housing and polycarbonate cover protect against mechanical damage and environmental impact.
• Compliance with standards: the product meets the requirements of PN-EN 60947-5-1 standard, which guarantees safety of use.
• Simple installation: maximum panel thickness is 6mm, which facilitates installation in various structures.
• Protection class: IP66/67 for the above-panel part and IP20 for the below-panel part provides protection against dust and moisture.
• Versatility: possibility of use in harsh industrial conditions and in building installations.

It is important to remember the appropriate cross-section of connection wires: 1x or 2x LY 0.75-1.5mm² or 1x or 2x DY 1-1.5 mm². The ambient temperature for N/2 execution is -15°C...+30°C and for W/3 -30°C...+50°C.
