Network choke D3N 40A/0.732mH 4% 19290-9964

Network choke – power protection and stabilization

This three-phase network choke from the D3N series, with a rated current of 40A and an inductance of 0.732mH, is a key element in ensuring stable and safe power supply to devices. Its design allows for effective suppression of interference, which translates into reliable operation of connected receivers. This choke is used in industrial, commercial installations and in power supply systems for sensitive electronic devices.

### Key features and application

The D3N choke is designed to operate in three-phase networks with a rated voltage of up to 750V. Its main function is to limit inrush currents when devices are switched on, which protects both the choke itself and the other elements of the installation. In addition, thanks to its anti-interference properties, it helps to reduce harmonics and improve power quality. The choke design also provides some protection against overvoltage.

* Limitation of inrush currents: Protects devices against sudden voltage surges during startup.

• Interference suppression: Reduces the impact of harmonics on power quality, improving the stability of devices.

• Application in three-phase networks: Adapted to work in installations with a voltage of up to 750V.

• High reliability: Solid construction guarantees long-lasting and trouble-free operation.

• Suitable as an anti-interference choke: Effectively reduces electromagnetic interference affecting device operation.

### Technical parameters and construction

The D3N choke is characterized by three poles on the input side, which ensures its proper functioning in three-phase systems. The IP00 protection class means there is no protection against access to live parts and against the influence of water and solids – therefore, the choke should be mounted in a protective housing or in a dry and well-ventilated place. The rated inductance at 0.732 mH provides optimal interference suppression parameters for a current of 40A. It is important to maintain appropriate operating conditions to ensure the long-term efficiency of the device.
