Mersen A4J225 - Class J Fuse 225A (200kA AIC @600V)

Mersen A4J225 is a low-voltage current-limiting fuse from the Amp-Trap family, designed for circuit protection in industrial power distribution systems. Rated for 600V AC/DC operation with a 225A current capacity, it provides 200kA interrupting capacity at rated voltage for reliable short-circuit protection. The single-barrel Class J fuse features a compact 2.13" diameter construction with robust ceramic body construction meeting UL/CSA standards. Its current-limiting design protects against fault currents in motor control centers, switchgear, and industrial control panels where high interrupting capacity is required.
