3-phase compensating choke INK 15-400V INK 3-15-400

Three-phase compensating choke – efficiency and installation protection

The INK 3-15-400 compensating choke is a key element in power factor correction systems, designed to operate in 400V networks. Its task is to reduce electricity costs by minimizing losses associated with the transmission of capacitive reactive power. The device is used in both industrial installations and commercial buildings with a large number of capacitive loads, such as LED lighting or UPS power supplies.

Application and benefits:

• Reactive power compensation: The choke effectively compensates for capacitive reactive power, improving the power factor and reducing network load.
• Reduced energy costs: By optimizing energy use, the choke helps lower electricity bills.
• Installation protection: Protects the circuit against overload and short circuit - like most circuit breakers in this class. Thermal protection in standard equipment provides an additional level of safety.
• Increased energy efficiency: A properly selected and installed choke increases the energy efficiency of the entire system.
• Long-term operation: Copper (Cu) windings and vacuum impregnation with class H varnish guarantee the reliability and long service life of the device.

Construction and parameters:

The INK 3-15-400 choke is characterized by a solid construction and high quality workmanship. It has a protection degree of IP00, which means there is no protection against the ingress of solid objects and water - therefore it requires installation in a dry and well-ventilated place. It is equipped with a thermal bimetallic trip switch, which provides effective protection against overloads. The device operates at a frequency of 50Hz and is designed to operate in an ambient temperature of up to 40°C. Its inductance is 34.9 mH at a power of 15 kVar and a rated current of 21.6 A. The choke meets the requirements of PN-EN 60076-6, which confirms its compliance with applicable safety and quality standards.

It is important to select the choke correctly for the specific operating conditions of the electrical installation to ensure optimal performance and reliability of the reactive power compensation system. Installation should be carried out by a qualified electrician in accordance with the manufacturer's instructions.
