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.

Fusible ATM Fast-Acting Midget
Amp-Trap ATM midget fast-acting fuses are rated 600VAC and 600VDC with a 100kA interrupting rating. These ratings give the ATM a wide range of applications not covered by other midget fuses. In addition, ratings of 30/35, 30/40 and 30/50 amperes are offered for specific applications such as capacitor protection.
Fusible A70QS Amp-Trap Form 101
A70QS Amp-trap Semiconductor Protection fuses were developed in response to the need for improved overall performance of 700 volt semiconductor fuses for new equipment requirements. A70QS fuses have lower I²t for better protection, longer life when subjected to cyclic loading, plus lower watts loss. A70QS is the best choice to protect dynamic solid state equipment such as motor drives, UPS, etc.

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 A70QS French Cylindrical
These Premium Amp-trap French Cylindrical Semiconductor Fuses are an extension of the popular A70QS product line. They are solid-fill 14mm and 22mm fuses IEC rated 690VAC, 200kA Interrupting and 700VDC, 100kA interrupting at 10ms time constant. In addition, these fuses have an 890 VDC rating for capacitor discharge applications up to 2.5ms time constant. All ampere ratings are available with a striker. Applications include small inverter drives and UPS systems, with superior I²t for improved protection and performance.

Fusible ATQR Time-delay/ Class CC
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 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.
