Product Overview
NJR2-T series soft starter is suitable for three-phase 220V voltage level soft starter, is based on advanced dual-CPU control technology as the core, controls the thyristor module, realizes the soft start and soft stop functions of (squirrel cage) three-phase AC asynchronous motor, and has a number of protection functions such as overload, input phase loss, load short circuit, starting current limiting timeout, overvoltage, undervoltage, etc. This product is mainly used with a complete set of control cabinets, and must be equipped with AC contactors for bypass of corresponding specifications in use. The product specifications cover 7.5 kW to 160 kW (squirrel cage) three-phase AC asynchronous motor, which is an ideal replacement product for traditional Y-△ starting and auto-coupling step-down starting.
Comply with standards: GB/T 14048.6, IEC 60947-4-2.
