Eaton 3A Fast Acting Melamine Cartridge Fuse 10 x 38 mm, 600V AC KTK-R-3

Eaton KTK-R-3 model is a 3 Ampere fast acting melamine cartridge fuse with dimensions 10 x 38 mm, engineered for industrial electrical protection at 600V AC. It is designed to safeguard control panels, motor control gear, and power supplies in automation and power distribution environments.

The fuse’s fast-acting characteristic rapidly interrupts short duration faults, effectively reducing peak fault energy to minimize damage to downstream components. The melamine construction of the body material ensures strong resistance against heat, electrical tracking, and thermal cycling, maintaining insulating properties over extended use.

Its 10 mm diameter allows for compact installations in standard cartridge fuse holders, and the 38 mm overall length supports its use in medium-voltage switchgear applications. The product meets UL 248-14 standards, emphasizing consistent safety and performance compliance.

Typical applications include protecting industrial control panels, motor control circuits, and high-voltage distribution modules. This fuse is an ideal replacement component in systems requiring fast-acting fuse characteristics for transient overload mitigation.

The fuse features a fast-acting F-speed characteristic that quickly interrupts short-duration faults. 3A current rating limits overload stress on protected circuits. Melamine body offers excellent resistance to thermal degradation and electrical tracking.

UL 248-14 recognized for standardized safety compliance. Compact 10 mm diameter size fits easily into cartridge fuse holders. Suitable for motor control gear, industrial electronics, and power distribution systems. The 38 mm overall length enables use in medium-voltage switchgear protection.

Designed to preserve downstream electronics and wiring by reducing peak fault energy.
