Description
Updated NJR series.
Did you know
- The Chint NJR2 series soft starter, including the NJR2-D model, was introduced around 2015. It was developed as an updated alternative to traditional star-delta and auto-transformer starting methods.
- The NJR2-D is part of the broader NJR2 series of soft starters, which also includes the NJR2-T and NJR2-ZX models. The NJR2-D is designed for three-phase 380V AC induction motors and requires an external bypass contactor, covering a power range from 7.5kW to 500kW.
- The NJR2-D is chosen for its ability to provide smooth starting and stopping of three-phase AC induction motors, which reduces mechanical stress and electrical surges. It features dual-CPU control technology, multiple starting modes, and comprehensive protection functions, making it suitable for a wide range of industrial applications.
| Model | Power Supply Voltage | Applicable Motor Power | Bypass Contactor |
