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 shortcircuit
conditions
Meets UL 94 flammability requirements with selfextinguishing/
non-flammable materials to prevent fires

Applications
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
Electrical vehicle chargers
