J TD FUSE 600V 300A AJT EI

J TD FUSE 600V 300A AJT EI

Item #: AJT300EI

Supplier Part #: AJT300EI
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.

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

H FUSE 250V 200A NRN

H FUSE 250V 200A NRN

Item #: NRN200

Supplier Part #: NRN200
Brand: Mersen

Mersen NRN (250V) and NRS (600V) fuses are standard non-time delay fuses, with a 10kA short circuit rating. 250 Volt NRN 15 amp through 60 amp fuses are certified as Type "P" fuses, satisfying the Canadian Electrical Code for low melting-point non-time delay fuses. Also qualifying for Type "P" are OTN15 through OTN60, which are Class K-5 fuses with a 50kA short circuit rating (found in the OT/OTS section of this cata log).

Type “P” (15 – 60A); 250V and 600V applications; Non-time delay

250V 175A 7 1/8x1 9/10 K5FUSE

Item #: OT175

Supplier Part #: OT175
Brand: Mersen

One-Time OT and OTN general purpose fuses provide low cost protection for feeder and branch-circuits serving lighting, heating, and other non-motor loads. OT and OTN fuses will safely interrupt available short-circuit currents up to 50,000 amperes in all ratings. OT and OTN fuses are not rejection fuses and care should be taken to ensure that replacement fuses do not have lower interrupting ratings than original fuses. OTN(15-60) satisfy the Canadian electrical code requirement for Type P low melting-point, non-time-delay fuses.

Resistive heating; Low cost for high protection value; Residential and small commercial installations; Easy to read imprint label for quick recognition and replacement; UL Listed to Standard 248-9 File E2137; Feeders; CSA Certified to Standard C22.2 No. 248.9 (The Canadian Electrical Code requires these fuses in ratings 15 through 60A to be of the low melting point design; use OTN 15-60.); Branch circuits; Self-certified for DC per UL248
