Description
Amp-Trap fast-acting A4J fuses deliver excellent current-limiting protection to a wide variety of applications. Their unique dimensions prevent the substitution of other fuses with lower voltage ratings, interrupting ratings, or current-limiting capability.
Features
- Engineered with highly advanced current-limiting technology, the Mersen Amp-Trap® A4J20 minimizes peak let-thru current during electrical faults. By isolating catastrophic overcurrent events within microseconds, it safeguards vulnerable solid-state devices, circuit breakers, and industrial machinery from severe thermal and magnetic damage.
- Featuring a massive 200kA interrupting rating at 600VAC (and 100kA at 300VDC), this Class J fuse safely extinguishes extreme fault currents without rupturing. This ensures your panelboards, switchboards, and feeder circuits remain fully compliant with stringent industrial electrical safety codes and localized arc-flash regulations.
- Built with precise Class J physical dimensions (13/16-inch diameter by 2-1/4-inch length), its unique ferrule terminal architecture acts as a mechanical rejection mechanism. This strict standard ensures maintenance technicians cannot accidentally substitute an inferior, low-rated fuse into a high-voltage, clip-mount terminal block.
- Operating with distinct fast-acting clearing characteristics, the A4J20 responds instantaneously to overcurrents, making it the perfect match for non-inductive systems like lighting networks, capacitive banks, and resistive heating elements. If your layout requires a time-delay mechanism to survive heavy motor-inrush surges without nuisance tripping, consider stepping over to the dual-element AJT series instead.
