Eaton Bussmann JJS-70 Fuse, Current-limiting Small Footprint VFD Line Protection, 70A, Class T, Bolted Blade End x Bolted Blade End, 200 kAIC at 600 V

The JJS-70 is part of Bussmann series’ Limitron fuse family and is a Class T, fast-acting, current limiting fuse. They are often used in Large apartment complexes, Multi-family meter stacks, and for VFD line protection, among other applications. Class T fuses are fast acting, current limiting fuses with a very small footprint. They are typically used where space in limited. They are commonly used in control panel boards, enclosed circuit panel boards for machinery, and safety switches. 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. 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.
