Cooper Bussmann LPJ-20SP Time-Delay Class J Fuse

Cooper Bussmann LPJ-20SP Time-Delay Class J Fuse is a dual-element protection device designed to guard electrical circuits against overcurrent while accommodating brief surge currents. As part of the Class J fuse family, the LPJ-20SP aligns with Cooper Bussmann’s LPJ line form factor and reliability standards for circuit protection in compatible equipment and enclosures. The dual-element construction provides redundancy and a more controlled response to fault conditions, allowing temporary overloads to pass during brief surges and ensuring disconnection when a sustained fault occurs.
