A70QS200-4 is a 200-ampere, 700V AC/DC rated Amp-Trap semiconductor protection fuse designed for dynamic solid-state equipment protection. This fuse features very low I²t for improved protection of sensitive equipment, superior cycling ability for long reliable life under high cyclic loading conditions, and low watts loss for cooler operation. With a 200kA interrupt rating (AC) and 100kA interrupt rating (DC), plus a 10ms L/R characteristic, it provides robust protection for motor drives, UPS systems, and inverters operating at 700V or less. The ultra-compact size allows for down-sizing of existing equipment while maintaining superior performance and reliability.
