Product Overview:

The KFW3 Series Universal Circuit Breaker (hereinafter referred to as "the breaker") is designed for use in AC distribution networks operating at 50Hz/60Hz with rated currents from 200A to 6300A. It has a rated insulation voltage of 1250V and is suitable for working voltages of AC230V, AC400V, AC500V, AC690V, AC800V, and AC1000/1140V. The breaker is used to distribute electrical energy and protect circuits and power equipment from overloads, undervoltage, short circuits, and single-phase grounding faults, while also providing isolation functionality.

The breaker can be equipped with various intelligent controllers, offering comprehensive protection functions. The communication-type controllers feature communication interfaces, facilitating connections with fieldbus systems and enabling remote monitoring, remote adjustment, remote control, and remote signaling (the "Four Remotes"), meeting automation control requirements. The breaker offers high precision in selective protection, minimizing unnecessary power outages and enhancing the reliability and safety of the power supply system..
