Phase sequence indicator NEF30WF 230V W0-NEF30WF

Phase presence indicator – reliable monitoring of three-phase circuits

This LED indicator, designated NEF30WF, is a simple but extremely useful tool for visually checking the presence of voltage in three-phase circuits. Signaling with three LEDs (red, green, and yellow) allows for quick identification of the status of each phase, which is crucial both during installation and operation. The metal housing ensures durability and resistance to mechanical damage, and the compact dimensions facilitate mounting in various applications.

Construction and application – robustness and functionality

The NEF30WF indicator is designed for mounting in 30 mm diameter holes. The metal body guarantees durability in harsh industrial conditions. Its main task is to signal the presence of voltage in each of the three phases, which facilitates diagnosing power supply problems and ensures work safety. Thanks to the use of LEDs, the indicator is characterized by low power consumption and long service life.

• Three-phase signaling: The red LED indicates the status of the first phase (L1), green – the second (L2), and yellow – the third (L3).
• Metal housing: Provides high resistance to mechanical damage and corrosion.
• Compact dimensions: Allow for easy mounting even in limited space.
• Low energy consumption: Thanks to the use of LEDs, the indicator is energy-saving.
• Complies with PN-EN 60947-5-1 standard: Confirms the safety and reliability of the device.
• Rated voltage 230V AC: Intended for standard electrical networks.

Installation and technical parameters – for professionals

The installation of the indicator is simple and intuitive – just place it in a 30 mm diameter hole and secure it with a mounting nut. It is important to pay attention to the correct connection of the connecting wires (1x or 2x LY 0.75 – 1.5 mm2 or DY 1 – 1.5 mm2). The indicator complies with the PN-EN 60947-5-1 standard, which guarantees its safe use. The rated insulation voltage is 500V for the NEF30WF model and 250V for other models in the NEF30 series. The degree of protection is IP66/67 for the above-panel part and IP20 for the below-panel part, providing protection against external factors. The operating temperature is -15°C...+30°C for the N/2 version and -30°C...+50°C for the W/3 version.
