Littelfuse IDSR Fuses Provide Exceptional Overcurrent Protection with Indication

























The time-delay, dual-element IDSR series fuses combine a 600 V dc capability with indication to provide an ideal solution for many dc applications. These fuses offer a patented, state-of-the-art, solid-state design with maximum reliability and superior performance characteristics.
- Excellent short-circuit protection
- Dual-element design
- Current-limiting
- Visual blown fuse indication
- Improves safety through faster response to fault currents
- Provides advanced short-circuit and overload protection
- Restricts fault currents to provide a high degree of circuit protection
- Indication window turns black allowing fast and easy identification of a blown fuse
