Semiconductor Protection Fuses

Round Body High-Speed Fuse-Links AC Protection

Amp-Trap® A70QS 700VAC 700VDC

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.
