Comparison of CHINT Contactor Series

Overview:

CHINT contactors are divided into:

Classic (CJX2/CJ20/CJX8), 업그레이드됨 (NXC/NC5), High‑Power (NC8), DC Special (CJZ8/NCZ5).

NXC fully replaces CJX2 with better performance; NC5 focuses on intelligence & modularity; NC8 covers ultra‑high current; CJZ8 is for DC control.

우선 사항: NXC / NC5; use special series for special applications.
