  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.

Overview

A low-voltage fuse is an overcurrent protection device designed for low-voltage electrical systems (typically defined as less than 1000 VAC or 1500 VDC). Its primary function is to interrupt fault currents during an overload or short-circuit event by melting its internal element, thereby preventing equipment damage or fire hazards. They are widely applied in all electrical and electronic systems requiring overcurrent protection, such as industrial power distribution systems, household appliances, automotive electronics, and new energy applications.
