LPJ-225SP - Bussmann - Fuse Class 'J' 225 Amp 600 Volt $129.99 As a time-delay fuse, it allows for temporary overload conditions without opening (sometimes called blowing a fuse). *50% higher IR (300kA) than any other UL and CSA fuse. Includes Class J, L, and R fuses. They respond quickly to overcurrents to ensure that sensitive equipment is protected from potential damage caused by short circuits or other fault conditions. 100 Amp Disconnect EATON Bussmann Series Low-Peak™ LPJ-90SP Current Limiting Time Delay Fuse, 90 A, 600 VAC/300 VDC 100 Amp Power Supply They are particularly useful to protect electronic devices and components that could be damaged by even short durations of overcurrent. These fuses are essential for enhancing electrical safety and protecting power systems because they work so quickly. This is necessary for equipment that regularly experiences short-term power surges, such as when a motor or transformer strarts up. Dual element fuses feature separate overload and short-circuit elements to provide the same short circuit protection as a fast-acting fuse with the added benefit of letting inrush currents pass without opening the fuse. The Bussmann series LPJ-100SP is a class J, low-peak, dual-element, current limiting, time-delay fuse. The time-delay feature allows an inrush current from the motor or transformer to start without opening but still protects against sustained overloads and short circuits. These low-peak fuses can also save money and space since one of these Low-Peak fuses can replace multiple fuses in a variety of applications. LPJ-100SP - Bussmann - Fuse Class 'J' 100 Amp 600 Volt $49.99 These devices are a critical component in ensuring a Code compliant, worry-free solution for electrical protection. A current limiting fuse can clear faults in one-half cycle or less. Eaton’s Bussmann series Low-Peak ultimate protection fuses are the industry’s only UL Listed and CSA Certified fuses with a 300 kA interrupting rating.
