The FZN25-12 series Indoor High Voltage Load Switch operate on a three-phase AC system with a frequency of 50Hz, designed for indoor installations at a rated voltage of 12kV. These switches find crucial application in a variety of settings, including industrial and mining enterprises, clinics, substations, and more. They serve as vital electrical protection and control devices for managing division and load current, loop current, no-load transformer operations, and cable charging current.

In urban distribution and industrial power setups, the FZN25-12 series load switch, in conjunction with the three-phase combination apparatus, proves essential. It ensures efficient load control and short circuit protection in three-phase ring networks or terminal power supply configurations. The combination with electrical transformers and other equipment enhances circuit reliability and cost-effectiveness, particularly benefiting ring networks, double radiation power supply units, and box-type substations.

Technical parameter

Product performance

1. Featuring both manual operation and AC/DC operation modes, it meets the requirements of a "three-remote" power system.

2. The isolation and elimination of the insulation plate effectively prevents internal arc short-circuit accidents caused by insulation board fractures.

3. The specially structured brake valve, load switch points, and automatic fracture isolation of the back door provide robust protection.

4. Copper contacts at the outlet and inlet lines have increased thickness to enhance conductivity while maintaining their original purpose.
