Description

Tri-Onic TR-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TR-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers.

Time-delay
Current-limiting
AC & DC rated
Optional solid state SmartSpot blown fuse indicator
Time-delay for motor start-ups and transformer inrush currents without nuisance opening
Current-limiting for low peak let-thru current
Rejection-style design prevents replacement errors (when used with recommended fuse blocks)
Easy-to-read label for quick brand recognition and replacement
Metal-embossed date and catalog number for traceability and lasting identification
Fiberglass body provides dimensional stability in harsh industrial settings
High-grade silica filler ensures fast arc quenching and high current limitation

AJT1 - Fuse Amp-Trap 2000® 600V 1A Time-Delay Class J AJT Series

Amp-Trap 2000® AJT fuses provide non-indication as well as a SmartSpot visual open fuse indicator. With advanced material technology the AJT fuse provides IEC Type 2 No Damage protection to main, feeder, and branch circuits, for all types of loads — yet, they require only half the mounting space needed for 600VAC Class RK fuses. AJT’s time-delay characteristics are ideal for handling typical motor and transformer inrush currents, while also providing superior current-limiting ability. Non-indicating or solid state SmartSpot visual blown fuse indicator Time-delay for motor starting and trans...
