Overview

The Littelfuse LS7R05002PS00L is a high-performance, energy-efficient 1500 V DC disconnect switch engineered for critical power management in demanding industrial environments. Designed to safely break or resume current flow, this 2-pole switch is essential for isolating circuits and preventing shock hazards during maintenance or system repairs. Its robust 1500 Vdc and 500 A ratings, coupled with a 10 kA SCCR rating, ensure reliable operation in high-voltage applications. Littelfuse's patented operation system is a key differentiator, minimizing arc damage upon disconnection to significantly enhance product reliability and extend its operational lifespan. The streamlined design eliminates the need for external bridging links, which not only reduces heat dissipation for improved energy efficiency but also simplifies installation, lowers maintenance time, and provides greater design flexibility due to a reduced footprint. This makes the LS7R05002PS00L an ideal choice for space-constrained applications. Safety is paramount with the LS7R05002PS00L. It features high-level disconnection insulation, creating a reliable barrier to prevent conduction when the switch is in the off position. Furthermore, the self-cleaning blade contacts ensure consistent performance over the product's lifespan by eliminating degradation caused by increased electrical resistance. The internally located, symmetrical "sandwich-type" 2-contact design is engineered to mitigate electromagnetic forces of repulsion, offering enhanced functionality and stability, especially during short-circuit conditions. Constructed with self-extinguishing/non-flammable materials meeting UL 94 V-0 flammability requirements, this switch actively prevents fire hazards.
