✅ CHINT NB1-63 C10 Miniature Circuit Breaker – 3P, 10A, C Curve, 6kA Breaking Capacity
Description (English):
The CHINT NB1-63 C10 is a triple-pole miniature circuit breaker (MCB) designed for three-phase systems in residential, commercial, and light industrial applications. With a rated current of 10A and a C tripping curve, it is suitable for balanced three-phase loads and equipment with moderate inrush currents.
It offers a rated short-circuit breaking capacity of 6kA at 400V AC according to EN/IEC 60898-1, and up to 50kA per EN/IEC 60947-2, ensuring reliable protection against overloads and short circuits across all three poles.
The breaker includes a toggle actuator for manual operation, a VisiTrip indicator for fast fault detection, and a VisiSafe strip for clear isolation confirmation. The compact 54mm width (3 DIN pitches) makes it ideal for modular panels.
Engineered for durability, it provides up to 20,000 mechanical and 10,000 electrical cycles. Additional features include 500V insulation voltage, 6kV impulse withstand voltage, and IP20/IP40 protection when installed in enclosures.
