3-phase compensating choke INK 4.5-400V INK 3-4,5-400

Compensating chokes – network optimization and cost reduction

INK 3 type compensating chokes are a key element in reactive power compensation systems. They are primarily used on long cable lines with insufficient load, in server rooms with UPS power supplies, and in facilities with a large amount of LED lighting. Their task is to increase energy efficiency and reduce costs associated with reactive power consumption. Thanks to them, energy transport becomes more efficient, and the installation is protected against the negative effects of reactive power flow.

Construction and application

INK 3 chokes are characterized by a solid construction based on windings made of copper (standard) or aluminum (on request). They are vacuum-impregnated with class H resin, which ensures their long-lasting and trouble-free operation even in difficult conditions. Protected with a bimetallic trip switch, these chokes provide effective protection of the circuit against overloads. Mounting is done using angle brackets, which facilitates installation and integration with existing electrical infrastructure.
