产品简介：
SET合金型温度保险丝是一次性不可复位的熔断装置，广泛应用于电器设备的过温保护。温度保险丝由具有低熔点的易熔合金
和助熔断剂构成，封装在塑料或陶瓷的外壳内。在正常工作情况下，易熔合金与两根引脚保持连接。当温度保险丝感受到异常发
热并达到预定的熔点温度时，易熔合金熔化，并在助熔断剂的作用力下快速彻底断开电路。有瓷管型和方壳型两种外形供选择，
额定电流1A~200A，动作温度76℃~221℃，安规认证包括UL，cUL，VDE，TUV，PSE，KTL，CCC和环保RoHS、REACH认
证。

术语解释：
● 热熔断体也称为热断路器或温度保险丝，在本文中这些不同名词都代表同样的产品，为一次性动作而不可复位的装置。
Thermal-link: also known as thermal cutoff or thermal fuse, all are the same in this context, function one only, non-resettable.
● 额定动作温度 Rated Function temperature (Tf ):
通10mA的负载电流时，加热使温度保险丝断开的温度。
The temperature of the Thermal-link which causes it to change its state of conductivity with a detection current up to 10mA
as the only load.
允许偏差 Tolerance: +0℃, -10℃ UL，VDE，IEC标准 Standard
允许偏差 Tolerance: ±7℃ （仅限PSE标准）only PSE
实测熔断温度 Fuse temperature (Fuse-temp):
置于油池中，通10mA以下的负载电流，每分钟升温0.5℃~1℃，测断开温度。
The temperature is measured with silicone oil bath of which temperature is increased at the rate of 0.5℃~1℃/ min, with a
detection current up to 10mA as the only load.
● 保持温度 Holding temperature (Th) :
持续通额定电流168小时不断开的最高温度。
The Max. temperature at which a TCO will not change its state of conductivity when conducting rated current for 168Hour.
● 极限温度 Max. temperature limit (Tm):
不破坏机械和电气特性所能承受的最高温度。
The Max. temperature at which the TCO can maintain its mechanical and electrical properties without being impaired for 10
mins.
● 额定电流 Rated current (Ir):
温度保险丝分类用，允许用于电路并安全断开的最大电流。
The current used to classify a Thermal-link, which is the Maximum current that thermal cutoffs allow to carry and are able to
cutoff the circuit in safety.
● 额定电压 Rated voltage (Ur):
温度保险丝分类用，允许用于电路并安全断开的最高电压。
The voltage used to classify a Thermal-link, which is the Maximum voltage that is allowed to apply to the circuit in which the
thermal cutoff is used.
● 瞬态过载电流Transient overload current (Ip):
温度保险丝在不破坏特性的情况下，所能承受的最大瞬态过载电流。
A direct current pulse train which the thermal-link is able to withstand without impairing its characteristics.
