Phoenix Contact NEF 1-10

The Phoenix Contact NEF 1-10 is a high-quality EMC filter designed to ensure the smooth operation of electrical equipment by mitigating electromagnetic interference in single-phase circuits. This filter is a vital component for industrial environments where electrical noise can cause disruptions in performance and reliability of machinery and systems.

Crafted with a robust polyamide housing, the NEF 1-10 is built to withstand the rigours of industrial settings. Its compact design, with a width of 40 mm, allows for easy installation on DIN rails, making it a versatile solution for space-constrained applications. The filter is suitable for mounting on both NS 32 and NS 35/7.5 DIN rails, providing flexibility in integration with existing setups.

The NEF 1-10 is rated for a nominal voltage of 240 V ac and can handle a continuous current of up to 10 A at an ambient temperature of 40°C. It features a maximum continuous voltage of 264 V ac across both line-to-neutral (L-N) and line-to-PE (protective earth) configurations, ensuring compatibility with a wide range of electrical systems.

With an impressive attenuation performance, the filter provides more than 80 dB of symmetrical and 40 dB of asymmetrical noise reduction at 1 MHz, making it an effective solution for maintaining signal integrity in noisy environments. The filter also includes a dual-stage design with capacitors and inductors to provide balanced noise suppression across a broad frequency range.

Connection to the NEF 1-10 is straightforward, thanks to its screw connection terminals that accommodate a range of conductor sizes from 0.2 mm² to 4 mm² for solid wires and 0.2 mm² to 2.5 mm² for flexible wires. The terminals are designed for a secure and reliable connection, with a recommended tightening torque of 0.8 Nm and a stripping length of 8 mm.

The NEF 1-10 is compliant with international standards, including IEC 60939-2 and EN 60939-2, ensuring it meets the rigorous requirements for EMC filtering components. Its flammability rating according to UL 94 is V-2, indicating a level of material safety in the event of exposure to fire.

In summary, the Phoenix Contact NEF 1-10 EMC filter is an essential component for industrial applications that require effective management of electromagnetic interference. Its durable construction, efficient performance, and ease of installation make it a top choice for engineers and technicians looking to maintain the integrity of their electrical systems.
