Square D BLO27160UPSKLP Fusible Pressure Switch

Square D BLO27160UPSKLP is a two-pole fusible pressure switch from Square D (Schneider Electric) rated for 1600 A, delivering protected, high-current switching in electrical power systems. This model combines a pressure-switch mechanism with fusible protection, intended for inline use in industrial or commercial distributions where large amperage switching with fuse integration is required. The BLO27160UPSKLP designation identifies this exact unit, and the two-pole configuration describes its basic electrical topology for installation and wiring planning. In practice, it’s used in heavy-duty power paths where a rugged switch must coordinate with fusible elements to isolate faults and protect downstream equipment. Engineers size feeders and control circuits around this type device, ensuring compatibility with downstream protection schemes and appropriate enclosure and mounting provisions for the installation environment. As part of Square D’s portfolio, these devices are commonly utilized in motor control centers, switchgear assemblies, and large distribution panels where robust protection and straightforward integration with standard fusing are advantageous.
