Descriere
Acest ComPacT NSX250B este un disjunctor fix, tetrapolar, complet 3P 3d, proiectat pentru a optimiza spatiul si capacitatea de rupere. Este o alegere optima pentru toate aplicatiile standard si specifice. Capacitatea de rupere (Icu) este de 25 kA rms la 415 V c.a. 50/60 Hz. Tensiunea de functionare este de 690 V c.a. 50/60 Hz. Acest produs incorporeaza o unitate de declansare termo-magnetica (TMD) cu un curent nominal de 250 A. Unitatea de declansare TMD ofera o protectie reglabila la suprasarcina termica si o protectie magnetica fixa. Aceasta versiune cu 3 poli (105 mm x 161 mm x 86 mm) este insotita de o varietate de functii si accesorii optionale. Este conform cu standardele internationale (IEC 60947), CCC, EAC si specificatiile maritime. ComPacT NSX250B face parte din arhitectura EcoStruxure Power de la Schneider Electric.
