Authorized Littelfuse Distributor
Littelfuse LFCL350C1 - Cable limiters are fusible devices that provide very fast short-circuit protection, primarily to faulted cables, but also to other conductors such as busway. Cable limiters do not have an ampere rating, and cannot be used to provide overload protection. Cable limiters are selected by cable size; for example, a 500 kcmil cable requires a 500 kcmil cable limiter. Their main use is to isolate faulted cables in circuits containing three or more parallel conductors per phase. They may be installed on the line side of the main service to provide short-circuit protection to the service conductors. This is especially important when service conductors are tapped from large low-voltage networks or from large low impedance transformers. Cable limiters have terminals which permit them to be installed in a variety of equipment. The most common configuration is the offset blade on one end and the crimp terminal on the other end. This permits the limiter to replace a cable terminal (lug).

Overview

The Littelfuse LFCL350C1 Cable Limiter is a specialized fusible device engineered for very fast short-circuit protection, primarily targeting faulted cables and other conductors like busway. Unlike conventional fuses, cable limiters are selected based on cable size rather than an ampere rating, ensuring precise application. For instance, a 500 kcmil cable necessitates a 500 kcmil cable limiter. Its principal function is to isolate faulted cables within circuits featuring three or more parallel conductors per phase. This device is crucial for safeguarding service conductors when they are tapped from large low-voltage networks or substantial low-impedance transformers, by being installed on the line side of the main service. The LFCL350C1 features versatile terminals, typically an offset blade on one end and a crimp terminal on the other, facilitating installation as a direct replacement for cable terminals (lugs) in various equipment. Key applications include: * Service Entrance Conductors * Secondary ties between transformers or network bus and bus-way terminal boxes * Feeders with three or more conductors per phase for shared heavy loads in large commercial and industrial settings * Multiple single conductor services tapped from single utility transformers in multi-family residential and small commercial installations Features: * Current-limiting characteristics protect conductor insulation and minimize damage during faults. * Proper application of cable limiters can allow for the use of equipment with reduced withstand ratings. * Available with a wide variety of terminations and cable ratings for diverse installation scenarios. This model is suitable for use with aluminum cables/conductors. For specific sizing guidance, contact Littelfuse Technical Support at 1-800-TEC-FUSE or [email protected]. The LFCL350C1 operates at 600 VAC and is designed for 350 kcmil cable sizes.
