NC2 Series AC Contactors

Function and Use

The NC2 series AC contactor (hereinafter referred to as the contactor) is mainly used in circuits with an AC frequency of 50Hz or 60Hz, a rated operating voltage up to 690V, and a rated operating current up to 800A. It is used to remotely connect and disconnect circuits, and can be combined with appropriate thermal overload relays to form an electromagnetic starter to protect circuits that may experience operational overloads.
