✅ CHINT NB1-63H C2 Miniature Circuit Breaker – 1P, 2A, C Curve, 10kA Breaking Capacity
Description (English):
This CHINT NB1-63H is a high-performance miniature circuit breaker (MCB) designed for enhanced protection in residential, commercial, and light industrial applications. It is a 1P circuit breaker with 1 protected pole, a rated current of 2A, and a C tripping curve, suitable for resistive and inductive loads with moderate inrush currents.
The MCB features a rated short-circuit breaking capacity of 10kA at 230V AC in accordance with EN/IEC 60898-1, offering robust protection against overloads and short circuits.
It is equipped with a toggle control mechanism, trip indicator, and complies with both industrial (EN/IEC 60947-2) and residential (EN/IEC 60898-1) standards. The VisiTrip indicator allows quick fault identification, while the VisiSafe strip ensures physical contact disconnection for safe downstream maintenance.
With mechanical endurance of up to 20,000 cycles and electrical endurance up to 10,000 cycles, this breaker ensures long service life. It is DIN rail mountable, with a compact 18mm width suitable for modular panels.
Additional features include a rated insulation voltage of 500V, impulse withstand voltage of 6kV, IP20/IP40 protection when enclosed, and a wide operating temperature range from -35°C to +70°C.
