457www.littelfuse.com 13FUSEHOLDERS For 3AG Fuses Low Profile Snap Mount Type APPROVALS:Recognized under the Components Program of Underwriters Laboratories and Certified by CSA. SPECIFICATIONS: Electrical: 348 Series: Rated at 15 amps for any voltage up to 250 volts. 344 Series: Rated at 15 amps at lamp voltage shown below. Dielectric Strength: 1500 volts minimum. When designing indicating type fuseholders into a circuit, consideration should be given to the resistance of fractional amperage fuses and the parallel resistance of the indicator lamp and its resistor. Mounting: Panel thickness range: .031" through .125". Molded Parts: Black thermoplastic body (UL 94V0). Thermoplastic bezel, cap and lens (UL94V2). See tables below for colors. Terminals: Brass. Tin-plated. Ambient Temperature: Non-indicating: – 40°C to +85°C. Indicating: – 40°C to +60°C. Fuse Installation: Insert a fuse into the cap and push the assembly into the body until it latches. Press in and down to unlatch for removal.
