The AJT20 is a 20A time-delay Class J fuse from the Amp-Trap 2000® series, providing advanced circuit protection. It is rated for 600VAC and 500VDC, with an interrupting capacity of 200kA AC and 100kA DC. This fuse features time-delay characteristics ideal for handling motor and transformer inrush currents, while its highly current-limiting design provides superior protection against short circuits. A solid-state SmartSpot visual indicator clearly shows when the fuse is open. Due to its small footprint and robust protection, it is commonly used in motor circuits, transformers, control panels, and for general load protection.
