✅ CHINT 169305 – NM8L 315A 3P RCCB 315A, 3-pole residual current MCCB with ultra-high 70kA breaking capacity and 100% Ics. Features X2-type earth leakage protection (0.1 / 0.3 / 0.5 / 1A), adjustable thermal magnetic trip unit, T1 delay settings, and NM8L-630 frame for high-demand industrial applications. 🔹 Description (English): The CHINT 169305 – NM8L-630S/400/3 X2 T1 is a heavy-duty residual current circuit breaker tailored for high-capacity industrial protection up to 315A. With a very high short-circuit interrupting capacity of 70kA and full Ics (100%), this MCCB ensures maximum system resilience. The X2 leakage protection (0.1–1A) is ideal for installations with moderate to high leakage current expectations. The breaker includes an adjustable thermal magnetic trip unit and T1-configurable delay (0.1 / 0.3 / 0.5 / 1s), providing flexible selectivity for complex electrical networks. 🔹 Key Features: • Rated current: 315A • Breaking capacity: 70kA (Icu), 100% Ics • Residual protection: X2 (0.1 / 0.3 / 0.5 / 1A) • Adjustable thermal magnetic trip unit • Configurable delay settings: T1 (0.1 / 0.3 / 0.5 / 1s) • Frame: NM8L-630 for heavy-duty applications • Compliance: IEC 60947-2 • Certifications: CCC, CE, KEMA • Mounting: DIN rail or panel 🔹 Technical Specifications (English): Parameter Value Model NM8L-630S/400/3 X2 T1 Part Number CHINT 169305 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
