The LPJ250SP by Schneider Electric is constructed as a dual-element, current-limiting fuse. It is rated for continuous operation at 250 A and is capable of managing a maximum AC voltage of 600 V and a DC voltage of 300 V. This component features a compact design with dimensions measuring Ø 2.00 inches × 3.38 inches (50.8 mm × 85.9 mm).
This fuse mounts using a bolt-mount blade mechanism, providing a secure installation. Its innovative dual-element internal design enhances its performance in current-limiting scenarios. A notable attribute is its ability to withstand inrush currents at five times its rated capacity for periods exceeding ten seconds, which protects downstream equipment from damage. The LPJ250SP also has an impressive AC interrupt rating of 300 kA at 600 Vac and a DC interrupt rating of 100 kA at 300 Vdc, ensuring it can handle substantial fault currents without failure.
Housed in melamine thermoset material, the insulator ensures durability and reliability in various temperatures and conditions. Provisioned with knife-blade ends in a bolt-through termination style, the unit allows for efficient connections. This fuse provides a selectivity ratio of 2:1 in ampacity coordination, enhancing its compatibility with different circuit configurations.
