3-phase compensating choke INK 1.0-400V INK 3-1,0-400

Compensating chokes – optimizing the operation of electrical installations

INK 3 type compensating chokes are elements used to correct the power factor in electrical installations. They are particularly useful in situations where capacitive loads occur, such as long cable lines, UPS power supplies or LED lighting. Their use allows for increased energy efficiency and reduced costs associated with reactive power consumption. The INK 3-1.0-400V choke is designed to operate in three-phase networks with a voltage of 400V and a power of 1 kVar.

Construction and application

INK 3 chokes are characterized by a solid construction based on a copper (Cu) winding and vacuum impregnation in class H varnish, which ensures long-term and reliable operation. They are designed for continuous operation (duty cycle 100%) and natural cooling (AN). The use of a bimetallic trip switch provides additional protection against overload. These chokes are used in various facilities, including server rooms, buildings with LED lighting and on long cable lines.

Key features and benefits

• Reactive power compensation: Effectively reduces the consumption of capacitive reactive power, which translates into lower electricity bills.
• Durable construction: Made of high-quality materials (copper, class H varnish) guarantees long life and reliability.
• Overload protection: The bimetallic switch protects the choke and installation from damage caused by overload.
• Easy installation: Mounting with angle brackets facilitates installation in various conditions.
• Wide range of applications: Ideal for compensating reactive power in various types of electrical installations – from server rooms to LED lighting.
• Suitable for 400V networks: Specifically designed to operate in three-phase networks with a voltage of 400V.
• Insulation class F: Ensures safe operation in standard ambient conditions (ambient temperature up to 40°C).

Thanks to its construction and properties, the INK 3-1.0-400V choke is an effective solution for improving energy efficiency and reducing operating costs of electrical installations for both professional installers and end users.
