Line choke (inlet) 4%, 3-phase for power 2.2 kW - 3 kW INS 3-8.0-400 INS 3-8,0-400

Line chokes – protection and optimization of drive system operation

The INS 3-8.0-400 line choke is a key element in electrical installations powering converter-based drive systems. Its main task is to limit inrush currents, which can negatively affect network stability and the lifespan of connected devices. Additionally, the choke reduces higher harmonics generated by inverters, improving power quality and minimizing interference in other devices.

This three-phase choke with 4% impedance is designed to work with loads from 2.2 kW to 3 kW. Its solid construction ensures reliable operation even in demanding industrial conditions. Installation is simple and intuitive, which translates to saving time and installation costs.

Construction and application

The INS 3-8.0-400 choke is characterized by compact dimensions (155 x 65 x 140 mm) and a weight of 3.2 kg. It is made of high-quality materials, which guarantees its durability and resistance to mechanical damage. Using a line choke in the inverter power supply system allows for:

• Limiting surge currents: Reduces network load during engine and other devices starting with high power demand.
• Harmonic reduction: Improves power quality, minimizing electromagnetic interference and impact on other devices.
• Increased device lifespan: Protects the inverter and connected devices from overloads and damage.
• Improved voltage stability: Provides a more stable power supply voltage for the inverter, which translates to its more efficient operation.

Key product features

The INS 3-8.0-400 choke is a solution dedicated to both professional installers and end-users looking for reliable protection of their drive systems. Its versatility makes it applicable to a wide spectrum of industrial and commercial applications – from simple automation systems to advanced production lines. The construction based on a core with a cross-section of 8x12 mm ensures optimal operating parameters while maintaining compact dimensions. This makes it possible to use it even in limited space.
