Product Overview

The CHINT NKB1-45 C/M3/06MLTG is an NKB1 Series Control and Protective Switching Device (CPS) designed for industrial motor control and protection applications. It integrates electrical switching, motor overload protection, short-circuit protection and auxiliary control functions into one assembly. This model features a 45A frame, a 3A rated operational current and an adjustable motor overload current setting of 1.2–3A. It is specified for an AC 400V main circuit, a separate AC 230V control supply and a 15kA short-circuit breaking capacity. The full model configuration includes residual current protection, communication and isolation functions. The photographed product shows a residual current setting label of 100mA with a 0.2-second delay. The supplied carton clearly identifies NKB1-45 C/M3/06MLTG, while the photographed product body identifies the NKB1-45 series. The complete device configuration and protection settings should be verified before installation or order fulfillment.
