Mersen A60X Amp-Trap Form 101 semiconductor protection fuse with bolt-in blade mount. These are popular for the protection of higher voltage heavy rectifiers such as traction rectifiers. They can carry long sustained overloads common with heavy duty apparatus. Low I2t minimizes damage to protected components on short circuit. Controlled arc voltage reduces stress to circuit components during fuse clearing. Choice of mounting types helps in equipment design. Current limiting. Applications: protection of heavy traction and electrochemical as well as rectifiers and other heavy-duty equipment. Approvals: UL recognized component; UL file E60314 and AC: UL guide no. JFHR2 (35-800A). Measures 11/16-inches diameter by 4-3/8-inches length.
