Mersen A50P450-4TA - Semiconductor Fuse 500V/450A (100kA AIC, VFA)

Mersen A50P450-4TA is a semiconductor protection fuse from the Amp-Trap family, designed for very fast-acting circuit protection in high-power electronic systems. This low-voltage fuse features a 500V AC/DC rating with a 450A current capacity and 100kA interrupting rating at 500V, housed in a compact bolt-in blade configuration for secure installation. Its VFA (Very Fast Acting) velocity characteristic ensures rapid response to fault conditions, while the semiconductor-class construction provides reliable protection for sensitive power electronics. Compliant with industrial safety standards, this fuse is commonly used in variable frequency drives, rectifiers, and other power conversion equipment requiring precise overcurrent protection.
