Ferraz Shawmut A25Z300-4 - Low Voltage Fuse 300A (100kA AIC @ 300V)

Ferraz Shawmut A25Z300-4 is a low-voltage current-limiting fuse designed for high-interrupting-capacity circuit protection in industrial applications. It features a 300V AC rating and 300A current capacity with a 100kA interrupting rating at 300V for reliable fault protection. The fuse employs a single-barrel bolt-in blade design with an EFA (Extremely Fast Acting) velocity characteristic for rapid response to overcurrent conditions. Compliant with industry standards for low-voltage fuses, it is part of the Amp-Trap family, engineered for demanding environments such as motor control centers, switchgear, and power distribution systems.
