NC6 series AC contactor is mainly used in AC 50Hz or 60Hz, rated working voltage to 690V, rated working current to 9A circuit, for remote connection and disconnection of the circuit, and can be used with appropriate thermal overload relay to form an electromagnetic starter to protect the circuit from possible operation overload.
The Carrier NC6 series AC contactor is designed for 50 Hz or 60 Hz circuits with rated voltages up to 690 V and currents up to 9 A. It can be used for remote switching and, together with a thermal overload relay, forms an electromagnetic starter.
The document specifies mechanical dimensions, installation requirements, environmental limits, coil voltage options, pole configurations, and detailed electrical performance such as pull‑in and release voltage ranges. Ordering instructions and optional auxiliary contacts are also covered. This manual is written in Chinese.
