Drag:<\/strong><\/p>\n

\u00d6versp\u00e4nningsavledare BR-25VG uppfyller kravklassen Klass I och Klass II enligt IEC 61643-11.<\/p>\n

Kraftfulla komponenter, l\u00e4mpliga f\u00f6r alla typer av vanliga kraftsystem.<\/p>\n

Visuell statusvisning.<\/p>\n

Enheten \u00e4r utformad f\u00f6r att anv\u00e4ndas mellan zon O och zon 1 (enligt IEC62305-4 definition av \u00e5skskyddsomr\u00e5de).<\/p>\n

Finns med fj\u00e4rrsignalering som tillval.<\/p>\n

Enkel standardskena montering.<\/p>\n

Anv\u00e4ndningen av h\u00f6gpresterande varistorer till\u00e5ter en snabb svarstid och en l\u00e5g skyddsniv\u00e5.<\/p>\n

Ans\u00f6kan:<\/strong><\/p>\n

\u2022 Dessa enheter skyddar l\u00e5gsp\u00e4nningsf\u00f6rbrukarsystem fr\u00e5n \u00f6versp\u00e4nning.<\/p>\n

\u2022 Den \u00e4r till\u00e4mplig p\u00e5 \u00e5skskydd f\u00f6r elsystemet i omr\u00e5den med h\u00f6g \u00e5skrisk (LPZ0B eller gr\u00e4nssnittet mellan LPZ0B och LPZ1).<\/p>\n

\u2022 Anv\u00e4nds i modul\u00e4r SPD Klass I + Klass II (Klass B + C) f\u00f6r TT och TN-S str\u00f6mf\u00f6rs\u00f6rjningssystem.<\/p>\n

Installation:<\/strong><\/p>\n

\u2022 Str\u00f6mmen m\u00e5ste st\u00e4ngas av f\u00f6re installation. Livedrift \u00e4r f\u00f6rbjuden.<\/p>\n

\u2022 Det rekommenderas att en s\u00e4kring eller str\u00f6mbrytare ansluts i serie vid \u00f6versp\u00e4nningsskyddets fr\u00e4mre \u00e4nde.<\/p>\n

\u2022 SPD installeras parallellt vid str\u00f6mf\u00f6rs\u00f6rjningens inlopps\u00e4nde av byggnadsf\u00f6rdelaren eller utrustningsrummet. Produkten \u00e4r installerad i typ styrskena. Om f\u00f6rh\u00e5llandena till\u00e5ter kan anslutningsl\u00e4get f\u00f6r Kevin anv\u00e4ndas.<\/p>\n

\u2022 Anslut enheten under installationen enligt installationsschemat, d\u00e4r L \u00e4r faslinjen, N \u00e4r neutrallinjen och PE \u00e4r jordlinjen. Koppla inte bort enheten. N\u00e4r installationen \u00e4r klar, sl\u00e5 p\u00e5 den automatiska str\u00f6mbrytaren och kontrollera om arbetsstatusen \u00e4r normal.<\/p>\n

\u2022 N\u00e4r SPD anv\u00e4nds, kontrollera statusen f\u00f6r feldisplayen regelbundet. Om felvisningsf\u00f6nstret \u00e4r r\u00f6tt eller om fj\u00e4rrterminalen avger en larmsignal, indikerar det att SPD:n \u00e4r felaktig och b\u00f6r repareras eller bytas ut i tid.<\/p>\n

\u2022 L\u00e4mplig f\u00f6r inomhusdrift, s\u00e5som installerad utomhus, m\u00e5ste vara utrustad med vattent\u00e4tt skal.<\/p>\n
