Series Features
Littelfuse FLSR Fuses Provide Exceptional Overcurrent Protection
Series DescriptionThe FLSR series dual-element, time-delay UL Class RK5 fuses are the most widely used fuse class. They offer superior performance and excellent protection for all types of circuits, especially those with motors. Precision manufactured parts ensure an accurate, consistent response to overloads and short-circuits. The FLSR fuses are also available in an indicating version, see the FLSR_ID series.
- Excellent short-circuit protection: Improves safety through faster response to fault currents
- Dual-element design: Provides advanced short-circuit and overload protection
- Current-limiting: Restricts fault currents to provide a high degree of circuit protection
