The Littelfuse LS7R 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. It is a 1500 V dc disconnect for ungrounded systems.
- The patented operation system minimizes damage caused by arcs upon disconnection to increase product reliability and longevity
- Streamlined design reduces footprint, speeds installation and maintenance, and eliminates need for jumpers to increase energy efficiency
- High-level disconnection insulation provides a barrier to stop conduction when switch is in off position for added safety
- Self-cleaning blade contacts prevent performance degradation due to increased electrical resistance over time
- Symmetrical “sandwich-type” design for internal contacts enhances functionality during short circuits by mitigating electromagnetic repulsion
- Meets UL 94 flammability requirements with self-extinguishing/non-flammable materials to prevent fires
