Over Current Protection（54）
- Miniature Fuses（26）
  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

SETsafe | SETfuse thermal protector (TMS) mainly uses bimetal disc to sense current or temperature. When the temperature of the bimetal disc reaches the pre-calibrated temperature, the bimetal disc quickly trips, connect or disconnect the circuit. Ambient temperature increasing or current increasing or both of the above may cause the temperature of the bimetal to reach its pre-calibrated temperature, thereby connect or disconnect the circuit. This device covers rated current from 0 to 20 A, rated operating temperature from 30 °C to 175 °C by various part numbers. It complies with RoHS and REACH environmental protection requirements.
