Abstract (en)
[origin: EP2919254A1] A surge protection device (100) with short-circuit protection function. The surge protection device comprises a surge protection module (102) and a short-circuit current protection module (101). The surge protection module discharges and suppresses a surge current and voltage, and the surge protection module is a plug-in type module. The short-circuit current protection module is integrated in a pedestal, and the short-circuit current protection module provides short-circuit protection and plug-in mounting for the surge protection module. The surge protection device overcomes the problems such as impact current brought by using an external overcurrent protection device as backup protection, while the surge protection device has a strong current limiting capacity, a good short-circuit breaking capacity, and a small minimal instantaneous tripping current value. The surge protection device can withstand a failure mode occurring in a temporary overvoltage (TOV), and can also play the role of protection in the case of a low current.
