ATQR small-dimension fuses feature time-delay characteristics ideally suited for the high inrush currents of control transformers, solenoids, and similar inductive loads. Mersen’s Amp-Trap 2000 ATQR fuses provide superior protection for the branch circuits of electrical distribution systems.
Fusible TR-R & TRS-R Time delay/ Class RK5
Tri-Onic TRS-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 TRS-R safely handle harmless starting currents and inrush currents associated with today’s motors and transformers.
Fusible AJT Time-delay/ Class JAmp-Trap 2000
Los fusibles AJT con retardo de tiempo Amp-Trap 2000 brindan protección IEC tipo “2” (sin daños) a los circuitos principal, alimentador y de derivación, para todos los tipos de cargas; sin embargo, requieren solo la mitad del espacio de montaje necesario para 600V UL Class Fusibles RK. Las características de retardo de tiempo manejan las corrientes de entrada del motor sin disparos molestos. Su capacidad de limitación de corriente y su amplio rango de calificaciones brindan una excelente protección contra sobrecorriente para todas sus aplicaciones. Un indicador opcional de fusible fundido y un microinterruptor está disponible en los fusibles tipo cuchilla (70 a 600 A) para una indicación visual y / o remota de fusible fundido.

FUSIBLE A2D-R - Class RK1 - Time-Delay
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 obsolete 250V Class H, K or RK5 fuses already installed in the field.
Fast-acting A3T Class T fuses combine two highly desirable features – high current-limitation and a small physical size. Their unique dimensions prevent the substitution of other fuses with lower voltage ratings or current-limiting capability. These fuses have glass melamine bodies for superior dimensional stability and catalog numbers stamped into the blades for permanent identification.

The High Speed Class J (HSJ) combines the low I2t of a semiconductor fuse and the branch-circuit performance of a Class J UL Listed fuse into a single design. The HSJ can provide both branch circuit protection per NEC requirements, as well as very low I2t for protection of power semiconductors such as Diodes, SCRs, GTOs and SSRs.
