Amp-Trap® A50QS 500VAC 500VDC
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.
