The CHINT Modular Contactor, specifically the NCH8-□M series, is primarily used as a remote or manual switch for controlling electrical circuits. It operates in power systems with AC 50Hz/60Hz frequency, rated for operating voltages up to 400V and operating currents up to 63A. The contactor is designed for applications involving non-inductive or low-inductive loads such as resistance furnaces, domestic appliances, and similar low-inductive applications. It switches circuits under AC-7a and AC-7b usage categories and should not be used to break short-circuit currents; appropriate short-circuit protection devices are necessary for such cases. The product conforms to IEC/EN standards and is suited for industrial applications needing reliable and manual or remote circuit control.
