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

600V 450A CLASS J HS FUSE

600V 450A CLASS J HS FUSE

Item #: HSJ450

Supplier Part #: HSJ450
Brand: Mersen

The High Speed Class J (HSJ) combines the low I2t of a semiconductor fuse and the branch-circuit performance of a Class J UL Listed fuse into a single design. The HSJ can provide both branch circuit protection per NEC requirements, as well as very low I2t for protection of power semiconductors such as Diodes, SCRs, GTOs and SSRs.

CSA certified to standard C22.2 no. 248.8; Drives; Excellent cycling ability for frequent starts/stops without nuisance opening; Optimized over-load capability for withstanding elevated levels of current during electronic motor controller starts; Electronic motor controllers; Control panels; Phase controllers; Solid state relays; Low I2t (low thermal energy); UL listed to standard 248-8 File E2137; Branch circuits; DC listed to UL 248; Soft-starters
