✅ CHINT NB1-63H C16 Miniature Circuit Breaker – 4P, 16A, C Curve, 10kA Breaking Capacity Description (English): The CHINT NB1-63H C16 is a 4-pole miniature circuit breaker (MCB) designed to provide full protection for three-phase + neutral electrical systems. With a rated current of 16A and a C curve tripping characteristic, it is ideal for moderate inductive and resistive loads such as distribution circuits, lighting panels, and small motor loads. It features a 10kA short circuit breaking capacity at 400V AC, ensuring strong fault protection and reliability. This breaker complies with EN/IEC 60898-1 and EN/IEC 60947-2 standards, making it suitable for industrial, commercial, and residential applications. Equipped with a toggle handle for manual control, VisiTrip fault indicator, and VisiSafe strip for safe disconnection visibility, it ensures ease of operation and maintenance. The device fits standard DIN rail mountings and has a width of 72mm (8 modules). Built to last, it supports up to 20,000 mechanical and 10,000 electrical cycles, and can operate between -35°C to +70°C. The breaker also offers a rated insulation voltage of 500V and impulse withstand voltage of 6kV.
