Abstract:
To provide a safety device capable of blocking a DC current with stability and with certainty.
A safety device 1 comprises: a temperature fuse 432 arranged between a DC power supply 41 and a resistor 22; and a capacitor 437 and a current fuse 436 connected in parallel to the temperature fuse 432.
