A4J225 - 225 Amp Fuse

A4J225 - 225 Amp Fuse

The Mersen A4J225 Amp-Trap® Class J Fast-Acting Fuse is built for electrical systems that need your reliable protection from overloads and short circuits. Rated at 225 Amps, this fuse is designed to open quickly during fault conditions, helping you protect equipment and reduce the chance of damage to electrical systems. It’s commonly used in commercial and industrial applications where keeping your equipment protected and minimizing downtime are important.

Part of the Amp-Trap® A4J series, the A4J225 provides current-limiting protection in a compact Class J design. The smaller footprint helps save space inside electrical panels and switchgear, while the Class J construction also helps prevent lower-rated fuses from being installed by mistake. That added level of protection can help you improve system safety in demanding environments.

The A4J225 is rated for 600VAC and 300VDC applications and is designed for use in power distribution systems, motor circuits, HVAC equipment, control panels, and manufacturing machinery. Its blade-style terminals provide secure clip mounting, and the GMG insulating body is made for dependable operation in everyday industrial conditions. With a high 200 kA interrupting rating, this fuse is capable of handling high available fault currents while helping protect connected equipment.

For facilities that rely on consistent electrical performance, the A4J225 offers straightforward and dependable overcurrent protection for a wide range of applications.
