Mersen/Ferraz Shawmut TR45R Tri-Onic Time-Delay Class RK5 Fuse, 45A 250V — Lot of 7

This lot includes seven (7) high-performance TR45R (45 Amp) Class RK5 fuses manufactured by Mersen (formerly Ferraz Shawmut). These Tri-Onic® dual-element fuses are engineered to provide reliable overcurrent protection for both motor and non-motor circuits, specifically designed to handle the high inrush currents typical of industrial equipment without nuisance tripping.  Advanced Protection: Features a time-delay characteristic that withstands harmless startup surges while providing superior protection against sustained overloads and short circuits.  Current-Limiting Performance: Effectively restricts peak let-through current to shield critical circuit components from damage during an electrical fault.  Safety Design: Includes a rejection-style feature that prevents the installation of incorrect fuse classes when used with appropriate Class RK5 fuse blocks.  Rugged Construction: Built with a glass melamine body for exceptional dimensional stability and high-grade silica filler for rapid arc quenching.  Technical Specifications (Per Fuse):Amperage: 45 Amps.  Voltage Rating: 250 VAC / 250 VDC.  Interrupting Rating: 200kA at 250VAC; 20kA at 250VDC.  Fuse Class: Class RK5.  Compliance: UL Listed to standard 248-12 and CSA Certified.
