A2K5R - 5Amp Fuse

A2K5R - 5Amp Fuse

The Mersen A2K5R Amp-Trap® Class RK1 fuse is made for circuits that need fast protection without added complexity. Rated at 5 amps, this fast-acting fuse helps protect electrical equipment from overloads and short circuits before they turn into bigger problems. It’s commonly used in branch and feeder circuits where dependable overcurrent protection is important for keeping your systems running safely.

One of the biggest advantages of the A2K5R is its current-limiting design. In the event of a fault, the fuse helps reduce the amount of damaging energy passing through the circuit. That can help protect your connected equipment, cut down on unnecessary wear, and reduce downtime in industrial or commercial settings. Its compact ferrule construction also makes it easy to install in compatible fuse clips and holders during maintenance or replacement work.

The A2K5R is rated for both 250VAC and 250VDC applications, giving it flexibility across different types of electrical systems. It also features tin-plated copper terminals for reliable conductivity and corrosion resistance.
