FLN36-24KV indoor AC high-voltage sulfur hexafluoride load switch is suitable for three-phase AC 50Hz, rated voltage 24kV ring network power supply or double-radiation power supply system, used for closing and breaking load current and overload current, and can also be used for closing and breaking no-load long lines, no-load transformers and capacitor banks, etc. The series combination of load switch and current-limiting fuse can replace the circuit breaker, that is, the load switch is responsible for closing and breaking various load currents, while the current-limiting fuse is responsible for breaking larger overload currents and short-circuit currents.
