When trying to isolate circuits or repair systems, the LS6R0250 dc disconnect switch quickly breaks or resumes the flow of current safely to prevent shock hazards. It has a total voltage rating of 1500 V dc and an amperage rating of 250 A. Available in a one-pole model.

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


  • Solar/PV systems: Combiner boxes, recombiner boxes and inverters
  • Energy storage systems: Disconnection of batteries, containerized batteries
  • Oil & gas: Dc drives
  • Railway: Earthing switches and battery disconnection
  • UPS: Switching and isolation of batteries
