KLM-1-1/4 is an electrical specialty fuse used to protect electrical circuits from overload or short-circuit. The fuse is designed for use in harsh industrial environments and can be used for high voltage and alternating current (AC) applications. This fuse is also able to protect against reverse polarity, voltage surge, and overcurrent conditions.

The working principle of the KLM-1-1/4 comprises of a current carrying element and a time delay element. The current carrying element consists of a fuse wire which is attached to a support coil. The support coil has several turns of very fine gauged wire in order to keep the fuse wire in place. The fuse wire is heated when the electrical current passes through it and when the temperature of the wire rises above the melting point of the metal, the wire melts and opens the circuit. This interrupts the flow of current and therefore prevents damage or destruction to the equipment or circuit.

The time delay element in the KLM-1-1/4 helps to prevent nuisance tripping, by providing a delay period before the device trips when an overload or short-circuit occurs. The time delay is set by the manufacturer and is usually between 5 and 10 seconds.

The KLM-1-1/4 fuse is suitable for a variety of industrial applications, such as heating, ventilation, and air conditioning (HVAC), pumps, welding, and motor control. The fuse can be used with motors and pumps that require a higher level of protection from overheating, as well as short-circuits and over-voltage situations. The fuse is also suitable for other applications such as telecommunication networks, power grids, lighting systems, and electrical control systems.

The KLM-1-1/4 fuse is reliable and easy to install. It is available in different sizes and configurations and is designed for maximum operating current of 50 Amps at an AC voltage of 600V. The fuse carries an interrupt rating of 50kA and is UL listed for UL489, CSA, and CE standards.

In summary, the KLM-1-1/4 fuse is an effective and reliable protection device for electrical and industrial applications. The fuse is designed with a current limiting element that prevents the circuit from tripping in case of overload, while a time delay element prevents nuisance tripping. The fuse is UL listed and suitable for a variety of industrial applications.
