Line choke (inlet) 4%, 3-phase for power up to 15 kW INS 3-30-400

Product features

• Current inrush and harmonic limitation

The INS 3-30-400 line choke is a key element in electrical installations powering devices equipped with frequency converters. Its main task is to limit inrush currents, which can negatively affect network stability and extend the life of connected devices. Additionally, the choke reduces the occurrence of higher harmonics generated by converters, improving power quality and minimizing interference in the operation of other devices.

Construction and application

This choke, designed for operation in three-phase systems with a power of up to 15 kW, finds application in a wide range of industrial and commercial applications. It is ideal for use with various drives, pumps, fans and other devices using inverters. The construction based on a core made of silicon steel ensures high efficiency and reliability. Insulation class F (155°C) guarantees safe operation at elevated ambient temperatures. The IP00 protection class indicates that it is intended for mounting in electrical enclosures.

Key features and benefits

• Protection of the power supply network: Reducing inrush currents minimizes network load and prevents overloads.
• Improved energy quality: Limiting harmonics ensures a stable power supply and reduces electromagnetic interference.
• Extended device life: Reducing electrical stress translates into a longer life of inverters and other connected devices.
• Solid construction: Made of high-quality materials ensures reliable operation even in harsh industrial conditions.
• Easy installation: Compact dimensions (190 x 160 x 80 mm) and the possibility of mounting with angle brackets facilitate installation. The choke weighs 7.5 kg.
• Parameters tailored to needs: Adapted to work in 400V networks, it offers an inductance of 0.98 mH at a current of 30A.
