This series of products is a complete set of indoor power distribution equipment for three-phase AC 50Hz systems with rated voltage of 12kV and below, as a complete set of equipment for receiving and distributing electric energy. The F-C circuit is particularly suitable for controlling high-voltage motors and other loads that are frequently operated. In addition, due to the use of current-limiting fuses with high breaking capacity, the F-C circuit can be used in high short-circuit capacity systems to effectively protect short-circuit faults. It is mainly used for the control and protection of motors and transformers in nuclear power plants. It can also be used by ordinary power plants, industrial and mining enterprises to close and disconnect AC high-voltage motors, transformers, induction furnaces and other loads, and has the functions of overload and short-circuit protection.

Product features:
1. High yield strength conductor fixture, can withstand high electromotive force requirements, solves the overlap and fixation problems between rectangular conductors and between rectangular conductors and equipment, and improves the vibration resistance of switchgear;
2. Rated short-time withstand current 50kA, rated peak withstand current 150kA, grounding loop short-time withstand current 43kA, grounding loop peak withstand current 130kA, rated short-circuit duration 4s;
3. The inside of the cabinet is divided into circuit breaker room, busbar room, cable room and instrument room by metal partitions. Each compartment of the main circuit system has an independent pressure relief device and channel, each compartment is reliably grounded, and is fully enclosed, with a protection level of up to IP2X, which can effectively control the spread of internal accidents. The switch cabinet has good sealing performance, and the shell protection level can reach IP42;
4. The switch equipment has undergone 5 OBE benchmark performance tests and 1 SSE safe shutdown earthquake resistance test, and the peak acceleration of the response spectrum is 4.68g in the X and Y directions and 6.44g in the Z direction;
5. The switch equipment has the ability to withstand extreme high temperature environments, with a humidity of 70%, a temperature of 50°C, and 72 hours of operation, which solves the problem of switch malfunction caused by environmental changes and meets the 60-year life aging requirements.
