    • An integrated fuse device (1) includes a varistor stack (11), a thermal fuse (12), and a current fuse (13) within an enclosure (2) having device terminals (3). The varistor stack (11) is connected to the thermal fuse (12) by a Cu terminal (20) and is connected to the device terminal (3) by steel terminal (10) of smaller cross-sectional area. Being of Cu material and having a greater cross-sectional area, the terminal (20) connected to the thermal fuse (12) has greater thermal conductivity than the steel terminal (10) to the end cap (3). The thermal fuse (12) comprises a plurality of links having a melting point to melt with sustained overvoltage, the links having a diameter in the range of about 2 mm to about 3 mm. The links pass through an elastomer plug (15), which exerts physical pressure on them to assist with opening during sustained overvoltage. Hot melt (18) around solder (17) of the thermal fuse limits heat conduction to back-fill sand.
    • 集成保险丝装置(1)包括具有装置端子(3)的外壳(2)内的压敏电阻堆(11),热熔丝(12)和电流保险丝(13)。 压敏电阻堆(11)通过Cu端子(20)连接到热熔丝(12),并通过较小横截面积的钢端子(10)连接到设备端子(3)。 作为Cu材料并且具有更大的横截面积,与热熔丝(12)连接的端子(20)具有比钢端子(10)至端盖(3)更大的热导率。 热熔丝(12)包括多个具有熔点以维持过电压的熔点,所述连接件具有在约2mm至约3mm范围内的直径。 连杆通过弹性体塞(15),其在其上施加物理压力以辅助在持续过电压期间打开。 热熔丝周围的焊料(17)周围的热熔体(18)将热传导限制为回填砂。
