250V 250A 8 5/8x2 1/16 K5FUSE

250V 250A 8 5/8x2 1/16 K5FUSE

Item #: OT250

Supplier Part #: OT250
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.

Residential and small commercial installations; 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.); Feeders; Resistive heating; UL Listed to Standard 248-9 File E2137; Low cost for high protection value; Self-certified for DC per UL248; Easy to read imprint label for quick recognition and replacement; Branch circuits

250V 250A RK1 TD FUSE

250V 250A RK1 TD FUSE

Item #: A2D250R

Supplier Part #: A2D250R
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.

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