Network choke D3N 25A/1.17mH 4% 19290-9966

Network choke – protection and stability in three-phase installations

This three-phase network choke from the D3N series, with a rated current of 25A, is a key element in ensuring stable and safe operation of electrical installations. Designed to suppress interference and protect against overvoltages, it performs well in both industrial and commercial applications. Its construction allows for effective limitation of harmonic currents, which translates to a longer lifespan of connected devices.

Construction and application

The D3N choke is designed to operate in three-phase circuits with a rated voltage of up to 750V. Its inductance of 1.17 mH provides effective suppression of electromagnetic interference, minimizing the impact of noise on sensitive electronics. The construction with three input poles guarantees symmetrical phase loading, which is important for the correct functioning of the network. These types of chokes are primarily used as filtering elements in power supply systems for motors, transformers and other devices generating interference.

Key features and benefits

• Effective interference reduction: Thanks to the inductance of 1.17 mH, the choke minimizes the impact of harmonic currents and electromagnetic interference on sensitive devices.
• Overvoltage protection: Helps protect connected devices from harmful overvoltages in the power supply network.
• Three-phase construction: Ensures symmetrical phase loading, which translates to stable operation of the installation.
• Wide voltage range: Suitable for operation in networks with a voltage of up to 750V AC.
• Suitable as an anti-interference choke: Optimized to reduce noise and interference in electrical installations.
• IP00 protection class: Indicates no protection against contact and ingress of solid objects and water – the choke is intended for mounting in protective enclosures.
