AJT3 - 3 Amp Fuse

AJT3 - 3 Amp Fuse

The AJT3 Class J Time-Delay Fuse is designed for your circuits that need reliable protection without unnecessary interruptions during startup.

Its compact Class J size makes it a good fit for electrical panels and control cabinets where space is limited. The current-limiting design also helps reduce the amount of fault current passing through the circuit during a short circuit, which can help protect your connected equipment and wiring from more serious damage.

The AJT3 uses a cartridge-style, non-indicating design that keeps your installation simple and dependable for everyday commercial and industrial applications. Whether it’s being used in motor controls, industrial machinery, HVAC systems, or branch circuits, this fuse is made for systems where dependable overcurrent protection matters.
