Eaton Bussmann LPJ-175SP Series LPJ Fuse, 175 Amp, 600 Vac and IR 300 kA / 300 Vdc and IR 100 kA

The Bussmann series LPJ-175SP is a class J, low-peak, dual-element, current limiting, time-delay fuse. These fuses are generally used in power panelboards, branch circuit breaker panelboard mains, machinery disconnects, and industrial controls, among other applications. 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. 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. This means they provide 50% more protection than any other listed fuse on the market*. They work by rapidly interrupting the flow of electrical current before it completes its first cycle which significantly reduces risk and protects your valuable equipment with the best technology available*. The high interrupting rating allows for simple, worry-free installation in virtually any application. 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. *50% higher IR (300kA) than any other UL and CSA fuse. Includes Class J, L, and R fuses. As a current limiting fuse, it reduces the magnitude of the current flowing through it during a short-circuit or other overcurrent event. This limits the potential damage to the electrical system and connected equipment by reducing the duration and intensity of the fault current. These fuses are essential for enhancing electrical safety and protecting power systems because they work so quickly. A current limiting fuse can clear faults in one-half cycle or less. This significantly limits the total electrical energy delivered to a fault and reduces the risk of an arc flash incident. These devices are a critical component in ensuring a Code compliant, worry-free solution for electrical protection. As a time-delay fuse, it allows for temporary overload conditions without opening (sometimes called blowing a fuse). This is necessary for equipment that regularly experiences short-term power surges, such as when a motor or transformer strarts up. 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. This also allows you to reduce the need to replace expired due to normal inrush overloads. Fast-acting fuses are designed to respond quickly when an overcurrent event happens. They respond quickly to overcurrents to ensure that sensitive equipment is protected from potential damage caused by short circuits or other fault conditions. They are particularly useful to protect electronic devices and components that could be damaged by even short durations of overcurrent.

• Used in specialized circuits and industrial control
• Current-limiting time-delay UL Listed and CSA Certified fuse with a 300kA interrupting rating that allows for simple, worry-free installation in virtually any application
• Space-saving package for equipment downsizing.
• Can often be sized for back-up protection against motor burnout from overload or single-phasing if other overload protective devices fail
