Item #: A2D150R

Supplier Part #: A2D150R
Brand: Mersen

Amp-Trap 2000 SmartSpot time-delay A2D-R fuses provide IEC Type 2 "no damage" protection to existing mains, feeders, and branch circuits serving motor and non-motor loads. A2D-R fuses will open fast enough under extreme fault conditions for maximum short circuit protection to prevent damage to motor starters, switches, and other circuit components, yet also provide the time-delay needed for motor in-rush currents. A2D-R fuses can be used to replace older 250V Class H, K or RK5 fuses already installed in the field.

CSA certified to standard C22.2 No. 248.12; Branch circuit protection; Recommended for Arc Flash energy reduction; UL listed to standard 248-12 File E2137; High-visibility orange label gives instant brand recognition; Metal-embossed date and catalog number for easier traceability and lasting identification; Motors; Reduced inventory by taking the place of class RK5, K, and H fuses; Rejection-style design prevents replacement errors (when used with recommended fuse blocks); All general-purpose circuits; Fiberglass body provides dimensional stability in harsh industrial settings; DC listed to UL standard 248; 600VAC & 600VDC dual rated; Disconnects; Safety switches; 300kA interrupting rating – self-certified, UL witnessed tests; Easy 2-to-1 selectivity for prevention of nuisance shut downs and “black outs”; Transformers; Solid state SmartSpot visual blown fuse indicator; Time-delay for motor starting and transformer inrush currents without nuisance opening; Extremely current-limiting for low peak let-thru current; Control panels

600V 300A CLASS J TD FUSE

Item #: AJT300

Supplier Part #: AJT300
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.

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