circuit protecting device

摘要

A circuit protection device is disclosed. The circuit protection device includes a case (10), an NTC thermistor (20), and a resistor (30). An input line (23) of the NTC thermistor (20) is connected to an input line (33) of the resistor (30) by an input connecting part (40). An output line (24) of the NTC thermistor (20) is connected to an output line (34) of the resistor (30) by an output connecting part (50). The thermistor (20) has a planar shape. The resistor (30) has a rod shape. The resistor (30) is arranged on the center of the NTC thermistor (20). A central line of a longitudinal direction of the resistor (30) is parallel to the NTC thermistor (20). Thereby, thermal imbalance is reduced by the mutual thermal influence of the resistor and the NTC thermistor.
