IntroductionThe JLLN-150 is a specialized type of fuse developed by Unison Electric. It is a low voltage application medium-grade fuse. This fuse has been designed and extensively tested to meet the demanding requirements of many different industries, including mining, power transmission and generation, telecommunications, and military applications. The JLLN-150 is an AC/DC application fuse with a unique operating principle to ensure it is safe and reliable. It is a medium-grade fuse offering simultaneous overload and short-circuit protection; the current-limiting characteristics of the fuse make it the ideal choice for many mission-critical tasks. Design and ConstructionThe JLLN-150 is constructed with two main parts: the fuse body and the fusible link. The fuse body is constructed from UL94V-0 rated thermoplastic and includes a riveted terminal contact, a fuse element holder, and a fuse holder clip. The fusible link is rated for up to 500A and provided an ultimate breaking capacity of up to 15 kA at 500 VAC. The unique construction of the fuse body makes it very durable as compared to other fuses, and it is able to withstand severe temperature and atmospheric conditions without affecting its ability to function properly. ApplicationGiven its current-limiting capabilities, the JLLN-150 is ideal for a wide range of applications. It is designed for use in indoor and outdoor locations, and is especially suitable for industrial-grade installations. It can be used for medium voltage distribution and control circuits, low voltage power supplies, and telecommunications systems. The current-limiting characteristics of the JLLN-150 provide effective overload, short-circuit, and transient overvoltage protection. Working PrincipleThe JLLN-150 fuse works by reducing the fault current to a safe level. This is achieved through the use of a fusible link, which is a short length of low-resistance conducting material that is connected in series with the load. The fusible link is designed to melt at a specific temperature, which is determined by the amount of current passing through the link. When a fault occurs, the current passing through the fusible link rises, causing the link to heat up until it melts. Once the link melts, the fault current is reduced to a level which is safe for the equipment and the surrounding environment. Safety FeaturesThe JLLN-150 fuse is engineered to provide superior protection from short-circuits. It is rated for a maximum voltage of 500VAC, and provides a breaking capacity of up to 15 kA at 500VAC. Additionally, it also offers effective protection against overvoltage transients, as well as overload. This ensures that the system is protected from damage caused by excessive current or voltage. ConclusionThe JLLN-150 is a specialized fused designed for use in a wide range of applications. It is a medium grade fuse, offering simultaneous overload and short-circuit protection. Its unique attributes make it ideal for many mission-critical tasks. Additionally, it is UL94V-0 rated and provides superior protection against overloads, short-circuits, and overvoltage transients.
