CKSG-146 146A 3 Phase AC Filter Reactor Inductor with Capacitor for Motor Control Cabinet
The CKSG-146 146A Three-Phase AC Filter Reactor Inductor is a high-performance electrical component specifically engineered for motor control cabinets, designed to work seamlessly with capacitors to optimize power quality and protect equipment.
Product Overview
With a rated current of 146A, this three-phase reactor adopts a dry-type, three-column core structure, featuring low loss and stable performance. It is perfectly matched with capacitors to form an efficient filter system, effectively suppressing high-order harmonics (especially 3rd, 5th, and 7th harmonics) and preventing parallel resonance, thus avoiding harmonic amplification and damage to capacitor devices.
Coil tightly wound with F-class high-temperature enameled wire
High insulation performance with temperature rise limits: ≤95K for coils, ≤85K for cores
Suitable for long-term stable operation
