Discover reliable, surge-tolerant protection for your electronics with the Jandorf S506 5A Time Delay Fuse. This compact, slow-blow fuse is engineered to withstand short inrush currents—from motor starts to transformer surges—without unnecessary outages, keeping your devices safe and online.
Designed for everyday electronics circuits, the S506 5A fuse is a perfect fit for power supplies, control boards, small motors, and heating elements where brief current spikes are normal. With a 250 V rating, it provides robust protection without compromising performance in common 5x20 mm fuse holders.
What makes this two-pack stand out:
-
Current rating: 5 A time-delay (slow blow) to tolerate inrush while protecting wiring and components
-
Voltage rating: 250 V, suitable for a wide range of AC applications
-
Construction: Glass tube with plated brass endcaps for reliable electrical contact and durability
-
Dimensions: 20 mm length, 5 mm diameter — fits standard 5x20 mm fuse clips
-
Package configuration: 2 fuses per carded package for easy stocking and quick replacement
-
Certifications: UL Listed and CSA Listed, ensuring safety compliance and quality
-
Series and usability: Sub Brand S506, trusted for consistent performance in electronics projects and professional assemblies
-
Tamper resistance: Non-tamper proof, straightforward replacement in standard setups
Ideal for hobbyists upgrading power supplies, technicians refreshing control circuits, or designers prototyping with motors and inductive loads. The Jandorf S506 fuse provides peace of mind by balancing protection and reliability—blowing only when truly needed, not during normal startup surges.
Why choose a time-delay fuse over a fast-acting one? When your device experiences transient spikes or brief inrush currents, a time-delay fuse protects both wiring and components from damage while avoiding unnecessary interruptions. This makes the S506 a smarter, longer-lasting safeguard for circuits with intermittent load changes or startup behavior.
Quick guidance for use: replace like-for-like with a 5 A, 250 V time-delay fuse in compatible 5x20 mm holders. Keep a spare from the 2-pack on hand to minimize downtime in critical systems—from lab benches to production lines.
