Amp-Trap 2000® A4BQ fuses are 20% more current-limiting than any
other Class L fuse on the market. When correctly coordinated, they
bring a superior level of protection to service entrance equipment.
Downstream circuit components have maximum protection against
short circuit let-thru current. A4BQ’s built-in, 4-second time-delay
characteristic (at 500% of rated current) accommodates harmless
inrush currents without nuisance opening.
Fusible ATMR - Class CC - Fast-Acting
Amp-Trap ATMR fast-acting fuses are the smallest dimension 600V fuses suitable for branch-circuit protection. The ATMR is a popular choice for economical protection of control circuits and control circuit transformers where available short circuit currents exceed 10,000 amperes. ATMR’s rejection dimensions prevent substitution by lesser rated fuses. These fast-acting fuses give current-limiting protection to general circuits.

Fusible A70P Amp-Trap Form 101
A70P Amp-trap Form 101 Semiconductor Protection fuses were developed for higher voltage AC and DC drives, UPS systems, reduced voltage motor starters and similar applications where lower I2t and superior reliability were needed. A70P is a very popular fuse, available in a wide range of ratings.
Fusible TRS-R - Class RK5 - Time-Delay
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 A3T - Class T - Fast-Acting
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.
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.
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 ATQ Time- Delay Migdet
Amp-Trap ATQ midget time-delay fuses are rated 500VAC with 42 ampere ratings from 1/10 to 30A. They are an excellent choice for supplemental protection of circuits where the available short circuit current does not exceed 10,000A. (Not for Branch Circuit Protection)

OT, OTN and OTS fuses are not rejection fuses -care should be taken to ensure that replacement fuses do not have lower interrupting ratings than
original fuses.
OTN 15 through 60 satisfy the Canadian electrical code requirement for Type «P» low melting-point, non-time delay fuses.
