✅ CHINT 101119 – NA1-2000X-1250M/4P MN–FX AC220/230(R) 4-Pole Air Circuit Breaker – 1250A, Fixed Type, Manual Trip (MN), 80kA Icu, AC220/230V 🔹 Description (English): The CHINT 101119 – NA1-2000X-1250M/4P MN–FX AC220/230(R) is a high-capacity 4-pole air circuit breaker (ACB) tailored for large-scale low-voltage distribution systems requiring comprehensive protection. With a rated current of 1250A, breaking capacity of 80kA (Icu), and 65kA Ics, this ACB provides robust fault clearing across all three phases and neutral. It features a manual trip mechanism (MN), a basic M-type intelligent controller, and fixed mounting (FX). Operating on an AC220/230V control circuit, it’s the ideal solution for transformer feeders, large motors, and power infrastructure. 🔹 Key Features: Rated current: 1250A 4-pole (3P + N) configuration High fault interrupting: Icu 80kA, Ics 65kA Manual undervoltage trip (MN) Fixed mounting (FX) M-type intelligent controller (basic) Control voltage: AC220/230V Designed for large motor starters and transformer lines Conforms to IEC 60947-2 🔹 Technical Specifications (English): Parameter Value Model NA1-2000X-1250M/4P MN–FX Part Number CHINT 101119 Rated Current (In) 1250A Breaking Capacity (Icu) 80kA Service Breaking Capacity (Ics) 65kA Frame Size 2000X Intelligent Controller M-type (Basic) Poles 4P (3P + N) Operation Type Manual Trip (MN) Mounting Type Fixed (FX) Control Circuit Voltage AC220/230V Compliance IEC 60947-2
