TAMURA NEC Microtemp 熱熔斷器 TF Cutoff 用於烘乾機加熱器

熱熔斷器 (總擁有成本) 是過熱保護元件. When the temperature inside the device or system exceeds the preset safety value, the TCO disconnects the circuit to prevent damage to the device or fire. This type of fuse is often used in electronic equipment, 汽車, and industrial equipment to provide additional safety. This article summarizes the working principle, structural characteristics, process flow, selection parameters, and design considerations of the thermal fuse.

Notes on the installation of thermal fuse:
1. When using lead bending, 它應該從一個零件彎曲超過 6 mm from the root; When bending, do not damage the roots and leads, and do not pull, 按, or twist the leads forcibly.
2. When the thermal fuse is fixed by screws, riveting or binding posts, it should be able to prevent mechanical creep and poor contact.
3. The connecting parts should be able to work reliably within the working range of the electrical product without displacement due to vibration and shock.
4. When welding the lead wire, 加熱濕度應限制在最低限度, and no high temperature should be applied to the thermal fuse; 請勿強行拉扯, 按, or twist thermal fuses and leads; 焊接後, 應冷卻超過 30 立即秒.
5. The thermal fuse can only be used under the conditions of the specified rated voltage, 當前和指定溫度. Pay particular attention to the maximum continuous temperature that the thermal link can withstand.
筆記: Nominal current, lead length and temperature can be Designed according to customer requirements.
N-F Series
