Prevent Shock Hazards with DC Disconnect Switch Line

The Littelfuse LS7R series, offered in 250, 320, 400 and 500 amperage at 1500 V, is an energy-efficient, compact disconnect switch that quickly break or resume the flow of current safely. These switches prevent shock hazards when isolating circuits or repairing systems in emerging applications that require higher current handling capability.

The LS7R dc disconnect switches have a streamlined design to eliminate the need for external bridging links or jumpers to lower heat dissipation. This increases energy efficiency as well as decreases installation and maintenance time for applications in photovoltaic and energy storage systems, electrical vehicle chargers, oil and gas, railway, and uninterrupted power systems.

The LS7R offers a patented operation system that minimizes damage caused by arcs upon disconnection to increase product reliability and longevity.

Key benefits of LS7R series of dc disconnect switches include:

  • a high-level disconnection insulation to provide a barrier to stop conduction when switch is in off position for added safety
  • self-cleaning blade contacts that eliminate performance degradation (from increased electrical resistance over time) to ensure consistent behavior across the product’s lifespan
  • an internally-located “sandwich-type” 2-contact symmetrical design to mitigate the electromagnetic force of repulsion to offer enhanced functionality in short-circuit conditions
  • Meeting UL 98B, UL 94, and IEC 60947-3 standards
