✅ CHINT NB1-63H C32 Miniature Circuit Breaker – 4P, 32A, C Curve, 10kA Breaking Capacity
Description (English):
The CHINT NB1-63H C32 is a 4-pole miniature circuit breaker (MCB) tailored for comprehensive protection in three-phase + neutral installations. With a rated current of 32A and a C-curve tripping profile, it is ideal for moderately inductive loads such as air conditioning units, industrial lighting circuits, and mixed load panels.
This circuit breaker provides a short-circuit breaking capacity of 10kA at 400V AC, fully compliant with EN/IEC 60898-1 and EN/IEC 60947-2 standards, ensuring safety and performance under fault conditions in residential, commercial, or industrial applications.
Features include a toggle-type manual actuator, VisiTrip fault indicator for easy troubleshooting, and VisiSafe for clear visual confirmation of contact disconnection. It mounts on a standard DIN rail and fits within 8 modules (72mm width).
The breaker is rated for 20,000 mechanical and 10,000 electrical cycles. Additional specifications include 500V insulation voltage, 6kV impulse withstand voltage, and an operating temperature range from -35°C to +70°C.
