Eaton Melamine Cartridge Fuse, 500mA, 600V AC KTK-1/2
Safeguard your equipment and appliances from short circuits and overcurrents with this cartridge fuse from the Eaton range. It's designed to serve as a weak link in an electrical circuit, cutting off the power supply to the system when a fault occurs to protect downstream devices from damage. With a breaking capacity of 100kA, this fuse can be used safely within a high current range without the risk of explosion or deformation. It's a reliable choice for general purpose use and can be commonly found in process control and industrial lighting circuits.
• Compact dimensions of 10 (D) x 38mm (L) for space efficiency in tight enclosures
• High rupturing capacity to handle high and low fault currents
• Voltage rating of 600V AC makes it suitable for low-voltage applications
• Light weight of 86g for easy handling and minimal system strain
What's the speed of this fuse?
This fuse is marked with a speed fuse of F. An F (Flink) speed fuse is fast-acting and gives an immediate response to faulty currents.
Eaton Bussmann Series Fast Acting Fuses - KTK
Eaton’s Bussmann series KTK fast-acting supplemental fuses for resistive loads such as control circuits, meter circuits and lighting circuit protection. These cartridge fuses have a melamine tube construction and nickel-plated end caps. For superior protection, Eaton Bussmann recommends upgrading to Low-Peak™ Class CC fuses.
What Speed is it?
These cartridge fuses are “F” speed rated, which is short for Fast Acting. This is also known as fast blow and is popular in general purpose applications. They are designed not to handle current spikes over the rated current.
What size is it?
These cartridge fuses are available in the compact size of 10x38 mm, also known as American Midget style fuses.
What voltage is it?
These cartridge fuses are available with 1 to 30 Amp current ratings for applications where the system voltage rating is 600 Volts AC.
What is Breaking Capacity?
Breaking capacity is the level of current that the fuse can safely handle without exploding or breaking. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit.
What are cartridge fuses used for?
• For the protection of components and equipment from costly damage used by over-current
• To isolate sub-systems from the main system once a fault has appeared
What is an overcurrent?
It is a setting where a circuit experiences a current that is higher than the normal operating current.
Features and benefits
• Color coded black for 600Vac voltage rating
• Fast-acting for resistive loads
• Melamine tube construction
• Nickel-plated endcaps
• Cylindrical body
