AJT30 - 30 Amp Fuse

AJT30 - 30 Amp Fuse

The AJT30 Class J Time-Delay Fuse is a practical choice for your electrical systems that deal with normal startup surges from motors, transformers, and HVAC equipment. When this type of equipment powers on, it can briefly pull higher current than usual. The AJT30 is designed to handle those temporary surges without opening too quickly, while still protecting the circuit if a short circuit or overload happens.

Its compact Class J design helps save space inside electrical panels and control cabinets, which can be helpful in tighter installations. The fuse also provides current-limiting protection, helping reduce the amount of fault current that passes through the system during a fault condition. That can help reduce damage to wiring, controls, and connected equipment.

The SmartSpot® visual indicator adds another layer of convenience during maintenance. When the fuse opens, the indicator gives technicians a quick visual reference, making troubleshooting faster and helping reduce downtime.
