A4J35 - 35 Amp Fuse

A4J35 - 35 Amp Fuse

The Mersen A4J35 Amp-Trap® fuse is designed for your electrical systems that need fast, reliable protection when fault conditions happen. Rated at 35 amps, this Class J fast-acting fuse helps protect circuits and connected equipment from overloads and short circuits before serious damage can occur. In commercial and industrial settings where downtime can quickly become costly, dependable overcurrent protection is an important part of keeping systems running safely.

The A4J35 reacts quickly during fault conditions to help limit the amount of damaging current passing through the circuit. That can help protect control panels, HVAC equipment, lighting systems, machinery, and other electrical components from unnecessary stress and damage. Its current-limiting design also helps improve overall system protection in applications with higher available fault current.

Another advantage is the Class J rejection-style design, which helps prevent lower-rated fuses from being installed by mistake. This added level of protection can help you support safer maintenance practices and more reliable system performance. The ferrule-style terminals provide secure installation in compatible fuse holders, while the PolyTube body is designed for long-term use in everyday operating environments.

With a 600VAC / 300VDC rating and a 200 kA interrupting capacity, the Mersen A4J35 is a practical choice for branch circuits, industrial equipment, power distribution systems, and commercial electrical applications that require fast fault interruption and dependable circuit protection.
