Detailed Description: Ferraz Shawmut Amp-Trap® A30QS Series Semiconductor protection fuse operates at a current rating of 70 Amps and voltage rating of 300 Volts. It has controlled arc voltage feature for reducing stress to circuit components during fuse clearing. Fuse with low l2t minimizes damage to protected components on short circuit and has very fast acting feature. It can be mounted using bolt-ins and blades. It is designed for providing protections to power semiconductors like diodes, phase control SCR's, AC/DC drives, UPS and other equipment of 300 Volts or less. It has an interrupt current rating of 1 - 4500 Amps/200 kilo-Amps at 300 VAC and 1 - 4500 Amps/100 kilo-Amps at 300 VDC. Fuse is UL recognized and RoHS compliant.
