600V 35A CLASS J HS FUSE

600V 35A CLASS J HS FUSE

Item #: HSJ35

Supplier Part #: HSJ35
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.

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

J TD FUSE 600V 45A AJT

Item #: AJT45

Supplier Part #: AJT45
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.

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