Product Description
The 1540-300 is an aviation fuse designed to protect aircraft electrical circuits from overcurrent conditions. When excessive current flows through the circuit, the fuse element opens, interrupting power to prevent damage to avionics, instruments, and electrical systems. Commonly used on avionics buses and distribution panels, this cartridge-style fuse mounts near the circuit source per aircraft maintenance data.
Selection and sizing follow MIL-PRF-15160 or MIL-PRF-23419 standards and comply with 14 CFR Part 25/27 electrical protection requirements. Replaceable design allows quick restoration of circuit protection during maintenance.
