Description
The Littelfuse JLLN050 delivers precision overcurrent protection where speed, reliability, and compact form factor matter most. Rated at 50 amps and 300 volts AC, this fast-acting Class T fuse features a current-limiting design that interrupts overloads and short circuits in milliseconds — safeguarding sensitive equipment, minimizing arc energy, and reducing the risk of costly system damage.
Built to fit where space is at a premium, the Class T form factor integrates seamlessly into control panels, switchgear, and power distribution assemblies. Its high interrupting rating ensures safe, dependable operation even in high fault-current environments, making it a trusted choice for engineers and electricians who demand consistent performance under pressure.
