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 Class C Canadian Fuses
Ferraz Shawmut Class C fuses have British standard
(BS88) dimensions and are exact replacements for
the British fuses and older HRCII-C fuses. Class C fuses are not dimensionally or electrically interchangeable with other North American fuses.
They feature ceramic bodies and bolt-in mounting.
They are for short-circuit protection only, in motor controllers, for example, where overload protection is provided by an overload relay.

Fusible Amp-Trap® A50QS Semiconductor protection
A50QS Amp-trap Form 101 fuses grew out of the need to improve the overall performance of semiconductor fuses in response to new equipment requirements. The A50QS encompasses the best protection features lower I2t to provide better protection for equipment, longer life when subjected to cyclic loading and lower watts loss. A50QS is today’s best choice for the protection of dynamic solid state equipment such as motor drives, inverters, 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 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 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 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.
