Açıklama

K8DT-PZ; Üç faz gerilim, asimetri, faz sırası faz kaybı rölesi

K8DT-PZ; Motorları ve diğer ekipmanları şebeke sistemindeki kararsız gerilimlerden korur. Üç fazlı sistemlerde aşırı gerilimi, düşük gerilimi, gerilim asimetrisini, faz sırasını ve faz kaybını tespit eder.

  • Motor çalışırken faz kaybı tespiti
  • Tüm 3 faz 3 kablo sistemlerde kullanılabilir (giriş gerilimi DIP switch ile değiştirilir).
  • İnverter gürültüsüne karşı daha fazla dayanım
  • Pano içinde gerekli alanı azaltmaya yönelik 17,5 mm genişlik
  • Kablolama işini azaltan Push-in Plus teknolojisi
  • Kuzey Amerika’ya kolay sevkiyat için UL onaylı
  • Çapraz kablolama için çift taraflı kablo yerleştirme imkanı (tüm terminaller)
  • Üstün kontak güvenirliği için transistör çıkışlı modeller
  • RoHS uyumluluğu
