A4J3 - 3 Amp Fuse

A4J3 - 3 Amp Fuse

The Mersen A4J3 Amp-Trap® Class J fuse is built for applications where fast circuit protection is important. Rated at 3 amps, this fast-acting fuse helps protect electrical systems and sensitive equipment from overloads and short circuits before damage has a chance to spread through the circuit.

The compact Class J design also helps prevent the installation of lower-rated replacement fuses, adding another level of protection in demanding environments. With a 600VAC and 300VDC rating along with a 200 kA interrupting capacity, the A4J3 is designed for applications that require dependable performance under high fault-current conditions.

Whether you're replacing an existing fuse or maintaining electrical equipment, the A4J3 offers a practical solution for dependable overcurrent protection.
