250V 50A 3x13/16 RK5 TD F

250V 50A 3x13/16 RK5 TD F

Item #: TR50R

Supplier Part #: TR50R
Brand: Mersen

Tri-Onic TR-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TR-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers.

High-grade silica filler ensures fast arc quenching and high current limitation; Motor circuits; General-purpose equipment; Easy-to-read label for quick brand recognition and replacement; Mains; Metal-embossed date and catalog number for traceability and lasting identification; Current-limiting; Time-delay; Service entrance equipment; Feeders; Current-limiting for low peak let-thru current; Rejection-style design prevents replacement errors (when used with recommended fuse blocks); AC & DC rated; Optional solid state SmartSpot blown fuse indicator; DC listed to UL standard 248 TRS only; UL listed to standard 248-12 File E2137; Branch circuits; Fiberglass body provides dimensional stability in harsh industrial settings; CSA certified to standard C22.2 no. 248.12; Time-delay for motor start-ups and transformer inrush currents without nuisance opening; Transformers

250V 40A RK1 TD FUSE

250V 40A RK1 TD FUSE

Item #: A2D40R

Supplier Part #: A2D40R
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.

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