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.
