In NT3, 'N' represents a low-voltage fuse, 'T' indicates a tubular structure, and '3' signifies the rated current-3A. This naming convention is like giving the fuse an ID card, allowing you to quickly understand its core parameters through the model number:
N series: Designed specifically for low-voltage circuits (voltage ≤ 1000V)
T-type structure: Cylindrical glass tube encapsulation, transparent design for easy observation of the fuse's state
3A rated current: When the circuit current exceeds 3A, the fuse will cut off the power supply within 0.1 seconds.
This design makes the NT3 a common overcurrent protection component in household circuits and small devices, like installing a 'smart switch' in the circuit.
