FLN36-12 AG High Voltage SF6 Load Break Switch Spacing 210mm
1.FL(R)N36-12D indoor high-voltage SF6 load circuit breaker is an indoor Switchgear with a rated voltage of 12KV. It uses SF6 gas as arc extinguishing and insulation medium. It includes three positions: closing, opening and grounding. It has the characteristics of small size, easy installation and use, and strong environmental adaptability.
2.Combining FL(R)N36-12D indoor high-voltage SF6 load circuit breaker with other electrical components can realize control and protection functions. It can be used for control and protection of electrical equipment in industrial and mining enterprises, civil power supply and secondary substations. Among them, the load switch-fuse combination electrical appliance matches the Transformer protection characteristics, which is particularly suitable for ring network power supply units.
3.FLN36-12D/630-20 indoor high-voltage SF6 load circuit breaker (hereinafter referred to as load switch) and FL(R)N36-12D/100-50 combination electrical appliance (hereinafter referred to as combination electrical appliance) comply with national standards GB3804 “3~63KV AC high-voltage load switch” (EQVIEC60265-1) and GBL6926 “AC high-voltage load switch-fuse combination electrical appliance” (EQVIEC420).
