✅ CHINT 169302 – NM8L 315A 3P RCCB 315A, 3-pole molded case RCCB with high 70kA breaking capacity and 100% Ics. Built on NM8L-630 frame with X2-type residual protection (0.1 / 0.3 / 0.5 / 1A), adjustable thermal magnetic trip unit, and configurable T1 delay settings. 🔹 Description (English): The CHINT 169302 – NM8L-630S/250/3 X2 T1 is a heavy-duty 3-pole residual current MCCB designed for mission-critical industrial power distribution systems. With a rated current of 315A and a very high short-circuit breaking capacity of 70kA, this breaker is ideal for protection in high-fault-level environments. Its X2 residual current detection (0.1 to 1A) suits installations with expected higher leakage thresholds. The breaker features an adjustable thermal magnetic trip unit and configurable T1 break time settings (0.1 / 0.3 / 0.5 / 1s) for flexible protection selectivity. 🔹 Key Features: • Rated current: 315A • High breaking capacity: 70kA (Icu), 100% Ics • Residual protection: X2 (0.1 / 0.3 / 0.5 / 1A) • Thermal magnetic trip unit (adjustable) • Break time settings: T1 (0.1 / 0.3 / 0.5 / 1s) • Frame: NM8L-630 • Standards: IEC 60947-2 • Certifications: CCC, CE, KEMA • Mounting: DIN rail or panel 🔹 Technical Specifications (English): Parameter Value Model NM8L-630S/250/3 X2 T1 Part Number CHINT 169302 Rated Current 315A Number of Poles 3P Breaking Capacity Icu: 70kA, Ics: 100% Residual Protection X2: 0.1 / 0.3 / 0.5 / 1 A Trip Unit Type Thermal-Magnetic (Adjustable) Break Time Settings T1: 0.1 / 0.3 / 0.5 / 1 s Frame Size NM8L-630 Mounting DIN rail or panel Standards IEC 60947-2 Certifications CCC, CE, KEMA
