Description
The Cooper Bussmann ABC-5-R is a high-performance, fast-acting supplemental cartridge fuse designed to provide precise overcurrent protection for sensitive electronic components, instruments, and control circuits.
Features
- Part of the premium Bussmann small-dimension series, the ABC-5-R is a heavy-duty, fast-acting supplemental fuse rated for a continuous current of 5 A at 250 V AC and 125 V DC. It is engineered to safeguard electronic equipment, power supplies, instrument panels, and minor control circuits, providing a precise sacrificial barrier that isolates localized faults before they cascade into expensive system processors.
- This fuse features an advanced fast-acting internal link design designed to clear overcurrent conditions with minimal time delay. Unlike slow-blow or dual-element fuses, it drops the line instantly when current thresholds are exceeded, making it the ideal protective choice for fragile, solid-state electronic devices and components that cannot tolerate sustained thermal overloads.
- Built to handle substantial electrical anomalies safely, the cartridge features an ultimate interrupting capacity (IR) rated at 200 A at 250 V AC, 10 kA at 125 V AC, and up to 10 kA at 125 V DC. This high fault tolerance ensures reliable containment of localized short circuits, instantly stopping high-energy arcs from bridging across internal electronic control boards.
- The "ABC" prefix designates a high-grade, non-transparent ceramic tube body construction, filled with a granular extinguishing medium and capped with heavy-duty nickel-plated brass endcaps. This ceramic configuration allows the fuse to handle significantly higher interrupting ratings and internal pressures than standard glass "AGC" fuses, eliminating the risk of shattering during severe high-current short circuits.
- Measuring a standardized 1/4-inch diameter by 1-1/4 inches in length, this traditional midget-sized cylindrical fuse drops natively into standard 1/4-inch fuse clips, open-face blocks, or panel-mounted finger-safe fuse holders. The "-R" suffix indicates that the component is fully RoHS compliant, manufactured with entirely lead-free materials to satisfy modern environmental initiatives.
- This device is strictly certified as a supplemental protection component and must not be used as a substitute for primary branch-circuit overcurrent protection (such as Class CC, J, or RK fuses). It is intended to be installed on the secondary or load side of a primary branch device to provide localized, granular protection within a specific piece of machinery or electronic chassis.
