Devices designed to carry out rated current for 4 hours minimum. It is recommended that
devices be operated continuously at no more than 80% rated current. See “Temperature
Re-rating Curve”for additional re-rating information.
Devices designed to be mounted with marking code facing up.

Notes：
1. DC Interrupting Rating tested at rated voltage with time constant < 0.8 msecs.
2. Nominal Resistance measured with < 10% rated current.
3. Nominal Melting I2t measured at 1 msec. opening time.
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.

保险丝(fuse)也被称为电流保险丝，IEC127标准将它定义为"熔断体（fuse-link)"。其主要是

起过载保护作用。电路中正确安置，就会在电流异常升高到一定的高度和热度的时候，自身熔

断切断电流，保护了电路安全运行。 [1]

一百多年前由爱迪生发明的保险丝用于保护当时昂贵的白炽灯，随着时代的发展，保护电力设

备不受过电流过热的伤害，避免电子设备因内部故障所引起的严重伤害。
