Product Q&A

Q:What are the available operating mechanisms?

The switch offers K type (single spring) and A type (double spring with fuse striker trip) manual mechanisms. Motorized and electromagnetic trip options are also available.

Q:What is the rated voltage and current?

The standard rated voltage is 12kV. Rated current options include 630A and 1250A depending on the specific model (FLN48-12D or FLRN48-12D).

Q:Is the switch suitable for outdoor use?

The product is described as an indoor switch. It requires an environment free from steam, corrosive gases, salt fog, and dust to ensure insulation performance.

Q:What is the mechanical life of the switch?

The mechanical life is rated for 5000 operations for the load switch and 2000 operations for the earth switch.

Q:How does the safety design work during internal arcing?

The housing features a weak point structure that releases overpressure and arc gas outwards through the cabinet shutter, ensuring operator and cabinet safety.
