Cartridge Fuse Holders Enclosed Fuseholders > Panel Mounted 344/348 Series Blown Fuse Indicating / Low Profile Holders for 3AB/3AG Fuses 344 Series (Indicating) 348 Series (Low Profile) Product Characteristics For 3AB/3AG Type Fuses Features Low profile design Blown fuse indicator 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 (UL94 V-0). Thermoplastic bezel, cap and lens (UL94 V-2). See tables below for colors. Terminals Brass. Tin-plated. Ambient Temperature Non-indicating: –40ºC to +85ºC. Indicating: –40ºC to +60ºC. 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. Dimensions Lens/Cap Bezel Body Recommended mounting hole .42" .87" Front .53" .85" .625 Sq.
