250V 90A RK1 TD FUSE

Item #: A2D90R

Supplier Part #: A2D90R
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.

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

93572-FUSEFORM 480

Item #: A60C125-121

Supplier Part #: A60C125-121
Brand: Mersen

Mersen low-voltage capacitor fuses provide advanced safety for power correction and harmonic filtering equipment. A capacitor fuse isolates a shorted capacitor before it can damage surrounding equipment or personnel. Typical capacitor failures occur when the internal dielectric can no longer withstand the applied voltage, resulting in a low impedance current path and generating excessive heat and pressure that can cause violent case rupture. Mersen A60C fuses will isolate the shorted capacitor before case rupture occurs while routinely withstanding inrush current at startup.

Capacitor inrush withstand capability; Tested by UL to CSA standard C22.2 No. 248.1; UL Recognized Component File E60314; Direct mount; High interrupting rating; Current-limiting; Optional blown fuse indication
