0.25A AGC Glass Tube Fuse – 5 Pack for Marine DC Circuits
The finest overcurrent protection in the AGC glass tube fuse range. This 5-pack of quarter-amp AGC fuses is designed for circuits where even the smallest overload could damage extremely sensitive electronics. Fast-blow design trips immediately under overload to protect delicate wiring and components before damage can occur.
The AGC glass tube format fits standard AGC inline fuse holders and legacy marine panels, making this a direct replacement for any 0.25A AGC application.

Parts Desk Insights
The 0.25A AGC is the most specialized fuse in the glass tube range — it's a niche rating used in precision instrument inputs and antenna amplifier circuits where even a 0.5A fuse offers too much headroom. If you're not certain this is the right rating, double-check your circuit's draw before ordering; most marine electronics circuits use 1A or higher. For a complete inline fuse solution, pair with the Inline AGC/MDL Fuse Holder – BSS-5063. For higher amperage ratings in this family, see the 0.5A 5-Pack (BSS-5202), 1A 5-Pack (BSS-5204), 1.5A 5-Pack (BSS-5205), 2A 5-Pack (BSS-5206), or 3A 5-Pack (BSS-5208).
