Over Current Protection（59）
- Miniature Fuses（25）
  Miniature Fuses
  Miniature Fuses is an Over Current Protection device. Its resistance is very low. When the circuit works normally, it is equivalent to a wire, which can conduct the circuit continuously and stably. When the current fluctuates due to circuit instability or external interference, it should also be able to withstand a certain range of overload. Only when overload or short circuit happens, Miniature Fuses can blow fast to protect the circuit. SETsafe | SETfuse Miniature Fuses is widely used in all kinds of electrical equipment. It has a variety of mounting modes, compact structure, reliable and stable performance. Technical parameters of SETsafe | SETfuse Miniature Fuses: Its rated current ranges from 0.1 A to 40 A, rated voltage ranges from 125 VAC to 500 VAC, and from 24 VDC to 600 VDC, complies with RoHS and REACH, and is approved by cURus, VDE, PSE, CCC, CQC, KC, TUV.
