Mersen A4J15 Fuse Amp-Trap 600V 15A Fast-Acting Class J, 0.81 Inch Dia, 2.25 Inch Length

Description

Features

• Engineered as a premium current-limiting device, the Mersen Amp-Trap A4J15 features low peak let-thru current capabilities to isolate faults instantly. This rapid response prevents destructive thermal and magnetic energy from damaging downstream panelboards, load centers, and solid-state equipment during a short circuit.
• Featuring a dedicated Class J physical rejection footprint, this 15-amp cylindrical cartridge has unique dimensions (13/16 in diameter times 2-1/4 in length) that accommodate standard ferrule clip mounting. This fail-safe geometry mechanically blocks maintenance personnel from mistakenly substituting lower-rated or non-current-limiting fuses, ensuring code compliance and keeping the facility secure.
• Boasting a robust dual-rating of 600 VAC and 300 VDC, this versatile fuse delivers high-performance protection across varied infrastructure types. It is an ideal drop-in choice for industrial feeder circuits, lighting arrays, heating loads, and DC motor controls, consolidating your facility's spare parts inventory.
• Built to handle catastrophic electrical events, the A4J15 features a massive 200,000-amp interrupting rating at 600 VAC and a 100,000-amp rating at 300 VDC. This immense breaking capacity ensures the fuse cleanly quenches extreme arcs within its PolyTube body without rupturing or creating secondary safety hazards.
• Fully UL Listed to Standard 248-8 and CSA Certified to C22.2 No. 248.8, this fast-acting fuse simplifies passing strict electrical inspections. Its dimensionally stable, heat-resistant body guarantees reliable long-term performance under heavy industrial operational cycles.
