Tlačno stikalo B71A 1,5–4,5 bar – dvopolni presostat za črpalke, G 1/4" NN – AKCIJA
Koda: SI0B71APodroben opis izdelka
Tlačno stikalo B71A (koda SI0B71A) je presostat za neposredno krmiljenje elektromotorjev črpalk, kompresorjev ter gospodinjskih in industrijskih tlačnih posod. Primeren je za tekočine in pline, ki so kemično združljivi z njegovo notranjo membrano. Kontakti se pri naraščanju tlaka razklenejo, zato se črpalka ob doseženem nastavljenem tlaku izklopi in ob padcu tlaka spet vklopi.
Tehnični podatki
- območje nastavitve 1,5–4,5 bar, tovarniška nastavitev 1,4–2,8 bar
- histereza 1,0–2,1 bar pri najnižji in 1,2–2,3 bar pri najvišji nastavitvi, največ 2,3 bar
- dvopolno stikalo, kontakti iz srebrove zlitine, Ui 415 V~, Ith 15 A, AC-1 do 12 A, AC-3 do 3 A
- navojni priključek G 1/4" z notranjim navojem, stopnja zaščite IP20
- najv. temperatura tekočine 70 °C, temperatura ohišja od −15 do +60 °C, masa 0,35 kg
- ohišje iz udarno odpornega termoplasta, kovinski deli iz jekla, ozemljitvena sponka, dve kabelski uvodnici, skladnost z EN 60947-5-1
Nastavitev in montaža
Stikalo se vgradi neposredno v cevovod. Vklopni tlak se poveča s privijanjem regulacijske matice, izklopni tlak s privijanjem matice histereze. Brez kontaktorja krmili motorje do 3 A. Vgradnjo in priključitev električnih delov sme izvajati le oseba z elektrotehnično usposobljenostjo.

Pogosta vprašanja
Kakšen tlak je mogoče nastaviti na stikalu B71A?
Vklopni tlak v območju 1,5–4,5 bar. Tovarniško je stikalo nastavljeno na 1,4–2,8 bar.
Ali lahko stikalo neposredno krmili motor črpalke?
Da, dvopolni kontakt krmili elektromotorje do 3 A (AC-3) brez kontaktorja. Za motorje z večjim tokom je potreben kontaktor.
Kako se spremenita vklopni in izklopni tlak?
S privijanjem regulacijske matice se poveča vklopni tlak, s privijanjem matice histereze pa izklopni tlak. Nastavitev naj opravi strokovnjak.
