600V 600A CLASS J TD FUSE

600V 600A CLASS J TD FUSE

Item #: AJT600

Supplier Part #: AJT600
Brand: Mersen

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.

Time-delay for motor starting and transformer inrush; Control panels; CSA certified to standard C22.2 No. 248.8; Bus duct; Fiberglass body provides dimensional stability in harsh industrial settings; Mains; Feeders; DC listed to UL standard 248; UL listed; Non-indicating or solid state SmartSpot visual blown fuse indicator; Transformers; Load centers; Most current-limiting UL class fuse; Motor circuits; High-grade silica filler ensures fast arc quenching; Unique Class J dimensions prevent replacement errors; Recommended for Arc Flash energy reduction; Easy 2-to-1 selectivity for prevention of nuisance shutdowns; DC tested to UL standard 248; Extremely current-limiting for low peak let-thru current; Circuit breaker back-up; UL listed to standard 248-8 File E2137; Branch circuits; Small footprint requires less mounting space and allows smaller, more economical fuse blocks; Lighting, heating & general loads; IEC 60269-2-1; Optional EI indicator/switch mount for AJT70 to 600 open fuse indication; High-visibility orange label gives instant brand recognition; Metal-embossed date and catalog number for traceability and lasting identification; 300kA interrupting rating – self-certified, UL witnessed tests
