KTK-1 Description

Short technical summary and product information.

The KTK-1 is a 1A, 600VAC fast blow cartridge fuse manufactured by Eaton - Bussmann Electrical Division. It is designed for electrical and industrial applications requiring reliable overcurrent protection. The fuse has a high breaking capacity of 100kA at rated voltage, ensuring safe interruption of fault currents.

 

The fuse features a fast blow response time, making it suitable for protecting sensitive components that cannot tolerate even short overcurrents. It is housed in a standard 5AG package (10mm x 38mm) and requires a holder for mounting. The physical dimensions are 0.406" diameter by 1.500" length (10.30mm x 38.10mm).

 

This fuse is approved by CSA and UL, indicating compliance with North American safety standards. It is commonly used in industrial control panels, motor circuits, and other electrical equipment where compact size and high interrupting capacity are required.
