AJT25 - 25 Amp Fuse

AJT25 - 25 Amp Fuse

The AJT25 Class J Time-Delay Fuse is designed for your circuits that need reliable protection without opening during normal startup conditions. Equipment like motors, transformers, and HVAC systems often pull a temporary surge of current when they power on. This fuse is built to handle those short inrush currents while still protecting the system if an overload or short circuit occurs.

Its compact Class J design makes it a good fit for control panels and electrical equipment where space is limited. The AJT25 also provides current-limiting protection, helping reduce the amount of fault current that passes through the circuit during a short circuit event. That can help reduce damage to connected equipment, wiring, and electrical components.

The SmartSpot® visual indicator makes maintenance a little easier as well. When the fuse opens, the indicator provides a quick visual signal so technicians can identify the issue faster and spend less time troubleshooting.
