DC SWITCH 500VDC 400A 2P. When trying to isolate circuits or repair systems, the LS60400 dc disconnect switch quickly breaks or resumes the flow of current safely to prevent shock hazards. It has a total voltage rating of 500 V dc and an amperage rating of 400 A. Available in a two-pole model. Features Benefits 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 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
