Abstract
A hot-line inserting and removing apparatus is capable of inserting and removing a circuit unit while the apparatus is in operation. An overcurrent protection circuit is inserted in a power supply in the hot-line inserting and removing apparatus, and has a switch which changes its resistance to prevent a rush current from flowing into a capacitive component of a connected load for protection against an overcurrent at the time the circuit unit is inserted.
