The KD1-.05A is a Pushbutton Circuit Protector provides circuit protection similar to a fuse but does not require replacement after a fault. This resettable design allows your customer to stay online and eliminate downtime. The KD series circuit breaker is easily installed in a 5/8-inch round or D-shaped panel cutout similar to that used on conventional panel mounted fuse holders. It can be mounted from either the front or rear and is held in place by special hardware. Its 1/4-inch quick-connect terminals are solderable. The KD pushbutton circuit protector trips without delay on short circuit and with a controlled delay upon sustained overloads upon tripping, the contacts open with a positive snap action, thereby suppressing the arc.
