Modern electrical systems continue to increase their complexity and electricians need reliable fuses to ensure the safety and protection of high voltage circuits in industrial, commercial and residential settings. The LA070URD32KI0800 is a specialty fuse manufactured for the purpose of protecting higher voltage circuits from dangerous shorts and surges. This article outlines the application field and working principle of the LA070URD32KI0800. The LA070URD32KI0800 is a 700 Amps UL Recognized and CSA Certified Current Limiting Fuse with a Voltage Rating of 2.2 kV/6.4 kV. This specialty fuse is constructed using copper-tinned construction and is designed to be very reliable when it comes to protecting industrial grade control panels, transformers, switchgear and motor controllers from surges and overloads. Unlike conventional fuses, the LA070URD32KI0800 is designed with a “current-limiting” feature which limits the maximum current of the circuit in order to quickly reduce the dangerous energy released during a fault.

As a model of the Electrical, Specialty Fuses, the LA070URD32KI0800 has a silver plated zinc-alloy link cartridge element that quickly closes when excessive current starts flowing in the circuit and simultaneously trips an overload relay as a result. This action completely removes the current from the circuit and returns it to a safe state. The LA070URD32KI0800 is designed with a reliable, time-delayed tripping feature that enables it to withstand and protect against momentary short circuits due to system transients and arcing faults. It is also designed to trip before it reaches its maximum carry current.

The LA070URD32KI0800 fulfills the safety requirements of most domestic and international standards with its UL Recognized and CSA Certified construction. The element is designed from silver plated zinc-alloy link which offers superior performance and guarantees a high speed of tripping in the event of an overload. Additionally, the LA070URD32KI0800 is designed to withstand a maximum voltage rating of 6.4 kV and a melting I2t of 960 A2s.

The LA070URD32KI0800 is used in a variety of applications that require high short circuit current withstand capabilities and is especially suitable for the protection of transformers, switchgear and motor controllers. It is also mainly used to protect circuits with high short circuit currents, such as in factories and other industrial settings. This device has an operational temperature range of -40 to +85 °C, an operational humidity range of up to 95%, and can tolerate altitudes up to 2,000 m without degradation of performance.

The LA070URD32KI0800 can be used in multiple configurations. It can work in a stand-alone mode such as a traditional fuse or as part of a fuse-breaker combination, in which the electrical circuit is protected by two components with different functions such as the fuse and the circuit breaker. The LA070URD32KI0800 can also be used as a component in a larger electrical system, where it is used in tandem with other components such as protective relays, sensors, and fusing systems in order to ensure the overall protection of the entire system.

To summarize, the LA070URD32KI0800 is a high-performance electrical specialty fuse designed for short circuit protection and overload protection in industrial, commercial and residential settings. It is UL Recognized and CSA Certified, has a temperature range of -40 to +85°C (withstanding up to 2,000 meters of altitude without any performance degradation), and offers outstanding time-delayed tripping of the circuit in case of an overcurrent. The LA070URD32KI0800 can be used in multiple configurations, including stand-alone mode, fuse-breaker combinations, and as part of a larger electrical system.
