This twin-pack delivers reliable, surge-tolerant protection for everyday power supplies, instruments, and control boards, so you can prevent damage from overloads while accommodating brief startup currents.
-
Time Delay (slow-blow) design: Specifically built to withstand short-duration inrush and surge currents common in motors, transformers, and power supplies, reducing nuisance trips during startup.
-
Reliable safety certifications: UL Listed and CSA Listed, providing documented safety and compatibility for equipment and panels.
-
Premium construction: Glass tube with nickel-plated brass endcaps combines durability with dependable electrical contact in challenging environments.
-
Compact, compatible sizing: 1/4 inch diameter and 1-1/4 inch length fit a wide range of fuse blocks, panels, and compact electronics without crowding the circuit.
-
Two-fuse convenience: Carded packaging includes 2 fuses per package, making stocking and quick replacements straightforward for field service or maintenance.
-
Voltage rating and application: Rated for up to 250V, ideal for electronic circuits, control panels, and power supplies requiring solid protection with surge tolerance.
Who is this best for? engineers, technicians, and DIY builders who need dependable overcurrent protection that won’t trip during normal startup surges. The 4A time delay fuse is a practical choice when a circuit draws brief higher current than its running state—for example, safe enclosure fans, small action relays, or regulated power adapters. Compared to fast-acting fuses, it preserves device uptime by letting transient peaks pass while still safeguarding wires and components from sustained overloads.
Why choose Bussmann? Known for consistent fuse performance and a legacy of electrical protection, this 2-pack provides ready-to-use replacements that maintain continuity in sensitive electronics projects. For precise protection in electronic circuits, trust the combination of a 4A rating, 250V capability, and the time-delay design to keep your systems safe and reliable.
