✅ CHINT 107404 – CHINT G NJBK7-800/400/AC220V 80A~400A Motor Protection Relay Standard 3-phase motor protection relay rated for 400A, with adjustable current range from 80A to 400A, AC220V control voltage—ideal for large motors without the need for communication or analog output. 🔹 Description (English): The CHINT 107404 – G NJBK7-800/400/AC220V is a heavy-duty motor protection relay designed for high-current 3-phase motors in industrial applications. It supports a rated current of 400A with an adjustable setting range from 80A to 400A, providing solid protection against overload, locked rotor, undercurrent, and phase failure. This model operates on AC220V control voltage and is a standard non-communicative version, meaning it has no RS485 interface or 4–20mA analog output. It’s ideally suited for large motor panels that operate in standalone mode without integration into centralized control or SCADA systems. With rugged construction and full compliance with IEC/EN 60947-4-1, it ensures reliable and long-term protection in high-demand environments. 🔹 Key Features: • Rated motor current: 400A • Adjustable current setting: 80A–400A • Control voltage: AC220V • Protection functions: overload, undercurrent, phase loss, locked rotor • No analog or RS485 communication interface • Designed for large independent motor starters • Complies with IEC/EN 60947-4-1 🔹 Technical Specifications (English): Parameter Value Model G NJBK7-800/400/AC220V Part Number CHINT 107404 Rated Current 400A Current Setting Range 80A–400A Control Power Supply Voltage AC220V Analog Output Not available Communication Interface Not available Application Motor Protection Standard Compliance IEC/EN 60947-4-1
