Introduction

The LA070URD30TTI0200 is a special type of electrical fuse used in a variety of electrical applications. It\'s part of the company\'s UR Series of electrical fuses that have been specifically designed for use in a wide variety of environments, including both indoor and outdoor applications. The LA070URD30TTI0200 is an excellent choice for applications where safety and reliability are paramount, such as medical and medical research applications.

Specifications

The LA070URD30TTI0200 is a single element, UL recognized fuse, designed for use in higher amperage applications. It is rated for 30 amps maximum at 250 VAC, and is UL listed to UL508 safety standards. The fuse is made from carbon and glass-filled polyamide/epoxy resin and is designed to withstand temperatures up to 158°F (70°C). The physical dimensions of the fuse are 1.40” (35.6mm) in width and 1.14” (28.9mm) in height with a toroidal shape.

Application Fields

The LA070URD30TTI0200 is an excellent choice for a variety of high amperage applications. It is commonly used in medical imaging and medical research equipment, where reliable and safe performance is critical. The use of the LA070URD30TTI0200 also extends to military, aerospace and industrial control applications.

Working Principle

The LA070URD30TTI0200 fuse works in a similar manner to other electrical fuses, by detecting excessive or abnormal electrical currents and limiting the associated circuit’s current. A fuse is composed of two key parts; a current sensing element and an enclosure which rests over the sensing element. The current sensing element of the LA070URD30TTI0200 is made from a carbon and glass-filled epoxy resin. The sensing element works by heating up when current passes through it, and when the heat reaches a set level the sensing element melts. This causes it to break the circuit, and like other fuses, it needs to be replaced with an identical one in order to reset the circuit. The housing of the LA070URD30TTI0200 not only protects the current sensing element, but also contains a number of other useful features. One such feature is that of thermal insulation or backing, which provides a latch on the housing cover, and helps to reduce the amount of heat dissipated into the circuit. The housing cover also helps to reduce any risk of sparks, should the fuse be subjected to an overload or short circuit. Furthermore, the fabrication technique used to make the current sensing element has been specifically designed to provide the most reliable and safe performance under all conditions. The construction of the LA070URD30TTI0200 ensures that it is unlikely to develop loose connections, and can therefore provide safe and reliable protection in the most demanding of environments.

Conclusion

The LA070URD30TTI0200 is an excellent choice for a wide range of high amperage applications, such as medical imaging and research, military, aerospace and industrial control. It offers reliable and safe performance, thanks to its construction from a carbon and glass-filled epoxy resin, and its construction is designed to provide the most reliable and safe performance under all conditions. The fuse provides a latch on the housing cover to help reduce the amount of heat dissipated into the circuit, and it also reduces the risk of sparks, should the fuse be subjected to an overload or short circuit.
