These ratings include Tf (Rated Functioning Temperature), Th or Tc (Holding Temperature), Tm (Maximum Temperature Limit), and the electrical ratings. Please see the technical data sheet. 使用中须注意，每个型号的温度保险丝都有其特定的电流、电压规格以及温度规格，包括Tf （额定动作温度）、Th 或者 Tc （保持温度）、Tm (极限温度)以及其电流、电压的规格，详见数据。 【2】For reason of safety that a thermal-link is a non-repairable item and that, in case of replacement an equivalent thermal-link with the same catalogue number shall be used, mounted in exactly the same way. 基于安全原因，温度保险丝是不可修复的产品，替换时应使用同类别同型号的温度保险丝并且严格按照同样的方法正确安装。 【3】Install thermal-links so that their temperatures do not continuously exceed the Holding Temperature speci- fied in the individual specification. 安装温度保险丝时要确保其应用环境的温度不会超过其相应规格中的保持温度。 【4】The end product should be designed so that thermal-link detects only intended heat source (radiant, con- vection, and /or conductance).For example, in a heater application, thermal-link should not be heated through lead wire which will accelerate the fusing off of the thermal-link, In case of a transformer or motor application, where the temperature should be controlled in a transformer or motor coil, and thermal-link should have good heat conductive contact with the transformer or motor coil. 最终产品需要确保温度保险丝仅能从预定的热源处（辐射源、对流源、和/或热传导）感受温度。举例来说，如应用于加热器， 温度保险丝不能让导线过多受热，这样会加速保险丝熔化断裂；如用于变压器或发动机，温度应该由变压器或发动机线圈控 制，这时温度保险丝就需要与变压器或发动机线圈之间有良好的热传导。 【5】It is recommended that using the dummy thermal-link having an internal thermocouple to select the proper temperature rating and location of the thermal-link. 建议采用内置热电偶式的仿真温度保险丝来确定适合的温度要求和安装位置。 【6】Do not locate the thermal-link on an assembly subjected to severe continuous vibration. 勿将温度保险丝安装在可能经常出现剧烈振动的地方。 【7】The end product should be tested to ensure that potentially abnormal conditions do not exposed the ther- mal-link to the temperature exceeding its Tm. 需对最终产品进行测试，以确保潜在的异常状况不会导致温度保险丝超过其极限温度。 【8】The seal or body must not be damaged, burned or over heated. 保险丝的封口及主体不能受损，烧伤或者过度受热。 【9】Mounting design of the thermal-links 安装温度保险丝 9.1 Mount the thermal-link at the location where temperature rises evenly. 将温度保险丝安装在可使其温度可以平稳上升的部位。 9.2 Design the lead wire as long as possible and connect it in the way that tension or pressed torsion is not applied to the wire. 确保引脚足够长，且其安装方法不会造成强行按压、拉伸及扭转引脚之现象。 Safety Precautions 安全预防措施 Address:NO.8067 West Xiangan RD,Torch High-Tech Industrial District, Xiangan, Xiamen, China 361101 地址：厦门火炬高新区（翔安）产业区翔安西路8067号 邮编：361101 Http://Www.SETfuse.com 厦门赛尔特电子有限公司 Xiamen SET Electronics Co.,Ltd.

A flexible or bent heater lead or a cold, low resistance heater lead should be used to connect to thermal-link. 最终产品时应考虑到与引脚接触的零部件因膨胀及收缩所造成的应力、振动或其他运动，应采用柔韧的、易弯曲的引脚或者 低阻引线来连接温度保险丝。 【13】Resistance of connections should be monitored to ensure minimal resistance. Improper connections or secure may result in premature failure of the thermal-link. Samples of joints should be inspected to ensure ade- quate mechanical bonding of lead to connection wires. Improper connections can cause damage to the seal or other parts which may result in shorting or nuisance tripping of the devices due to the generation of excessive heat at a faulty high resistance junction. 应确保接触电阻为最小值，不正确的连接可能造成温度保险丝提前失效，需要对焊接样本进行检查以确保引脚和连接线充分地连 接，不正确的连接可能引起封口或其他部份的损坏，不良连接产生的高阻可能导致器件过热而引起短路或损坏。 【14】Splices and terminations引脚的结合以及末端材料 14.1 If it is necessary to bare the lead of wire, there shall be an arrangement that prevents deflection or damage of the thermal-link wires. 若必需外露一定长度的引脚，应该采取可以防止温度保险丝引脚歪斜或损坏的措施。 14.2 Terminals or clamps should be of corrosion resistance materials. 所采用的末端材料或夹具应为抗腐蚀材料。 14.3 Appropriate free lengths of wire and sufficiently flexible wire connections should be used. Thermal-links and splices should be secured to prevent vibration or flexing of thermal-links and splices during normal operation. 应采用长度及柔韧度充足的引脚,温度保险丝和连接线的结合应该是可靠的，以避免其在正常工作状态下发生振动或弯折。 Safety Precautions 安全预防措施 Address:NO.8067 West Xiangan RD,Torch High-Tech Industrial District, Xiangan, Xiamen, China 361101 地址：厦门火炬高新区（翔安）产业区翔安西路8067号 邮编：361101 Http://Www.SETfuse.com 厦门赛尔特电子有限公司 Xiamen SET Electronics Co.,Ltd.

During this cooling time, never move the thermal-link body and lead wire. 焊接后应让其自动冷却20秒以上,在冷却期间，勿移动温度保险丝本体和引脚。 【16】Location of thermal-link with regard to wet application安装温度保险丝时应注意防潮 If thermal-link is applied to coffeepot, hot-water heater, dryer, hygrostat, etc., locate the thermal-link at the position where thermal-link is protected from breakage by spilling water or other liquid and from damage by high humidity. 如果温度保险丝是用于咖啡壶、热水器、干燥机、温度调节器等环境下，那么应将温度保险丝安装在无水泄漏和非高湿度的部 位。 【17】After Installation, the end construction shall comply with the appliance standard. 安装完成后，应确保整体结构符合应用的要求。 Function temperature Tf 额定温度℃ Max allowable soldering time (s) 最大允许焊接时间 Solder temperature 焊接温度 Length of Lead wire (L) 引线长度 10mm 20mm 30mm 102~115 1* 2 3 400℃ 116~135 1* 3 5 136~150 3 5 5 *Need to add auxiliary heat conduction for not damage the thermal fuse unexpectedly. *为防止温度保险丝被焊断，焊接时需要增加辅助散热装置。 Table 1.soldering time (Sec) 表1：焊接时间 (秒) Safety Precautions 安全预防措施 Address:NO.8067 West Xiangan RD,Torch High-Tech Industrial District, Xiangan, Xiamen, China 361101 地址：厦门火炬高新区（翔安）产业区翔安西路8067号 邮编：361101 Http://Www.SETfuse.com 厦门赛尔特电子有限公司 Xiamen SET Electronics Co.,Ltd.
