Description

The Littelfuse LS6R dc series is an energy-efficient, compact disconnect switch that quickly breaks or resumes the flow of current safely to prevent shock hazards when trying to isolate circuits or repair systems. Features/Benefits The patented operation system minimizes damage caused by arcs upon disconnection to increase product reliability and longevity Streamline design eliminates the need for external bridging links (jumpers) to lower heat dissipation for increased energy efficiency, decreased installation and maintenance time, and reduced footprint for added design flexibility High-level disconnection insulation provides a barrier to stop conduction when switch is in off position for added safety The self-cleaning blade contacts eliminate performance degradation (from increased electrical resistance over time) to ensure consistent behavior across the product’s lifespan The internally-located "sandwich-type" 2-contact symmetrical design mitigates the electromagnetic force of repulsion to offer enhanced functionality in short- circuit conditions Meets UL 94 flammability requirements with self- extinguishing/non-flammable materials to prevent fires

Applications
