_**KD Series Pushbutton Circuit Protector**_ 

## **Product Description** 

The KD 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. 

## **Features, Benefits and Functions** 

- Easy installation — The KD Series is easily installed in a 5/8” round or D-Shaped panel cutout similar to that used on conventional panelmounted fuse holders. It can be mounted from either the front or rear and is held in place by special hardware. Its 1/4” quick-connect terminals are solderable. 

- Resettable pushbutton circuit protector: 

- ❑ Provides basic thermal protection 

- ❑ Ratings from 0.25 – 20 amperes 

- ❑ UL recognized 

- Positive action — 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. 

- Protective covers — For applications where equipment may be exposed to dust or moisture, protective boots are available. Two styles are available, one which protects the breaker from splashing water and another which seals the panel opening.
