ABB AJT30N 30 Amp Class J Time-Delay Fuse 600V Non-Indicating

The ABB AJT30N is a 30 amp Class J time-delay fuse rated for 600VAC and 400VDC applications. This non-indicating version of the Amp-Trap 2000 series provides IEC Type 2 No Damage protection for main, feeder, and branch circuits across all load types while requiring only half the mounting space of traditional Class RK fuses.

Key Features:

• 30 amp current rating with 600VAC/400VDC voltage rating
• 200kA interrupt rating for superior circuit protection
• Time-delay characteristics ideal for motor starting and transformer inrush currents
• Current-limiting design provides superior arc protection and low peak let-thru current
• Class J rejection-style design prevents replacement errors
• Dual-element construction with fiberglass body for dimensional stability
• Ferrule terminal ends for secure clip mounting
• Non-indicating model without visual fuse status indicator

The time-delay characteristics make this fuse particularly effective for handling typical motor and transformer inrush currents while maintaining superior current-limiting ability. The compact Class J design allows for smaller, more economical fuse blocks and panel configurations. UL and CSA approved for commercial and industrial electrical applications.
