A2K4R - 4 Amp Fuse

A2K4R - 4 Amp Fuse

The A2K4R is a 4 amp Class RK1 fuse made for circuits that need fast, reliable protection. When a short circuit or overload happens, this fast-acting fuse responds quickly to help protect your electrical equipment from damage. Its current-limiting design also helps you reduce the amount of fault energy passing through the circuit, which can help protect connected components and reduce downtime.

With a 200 kA interrupting rating at 250 VAC, the A2K4R is well suited for commercial and industrial electrical systems where dependable overcurrent protection is important. The compact cartridge-style body makes it easy to install in control panels, machinery, HVAC systems, and other equipment where space may be limited.
