Ferraz Shawmut - Mersen AJT2-1/4 600V 2-1/4A CLASS J

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