Class T fuses are non-renewable, current-limiting, and conform to UL 198H. Current ratings range from 0A to 1200A for 300V rated fuses, and 0A to 1,200A for 600VAC rated fuses (DC ratings are also available). The interrupting rating is 200kA rms symmetrical and these fuses are designed for protection of feeders and branch circuits in accordance with the NEC. Class T fuses must be labeled "Current Limiting", and may be labeled "Time Delay" if they pass time-delay requirements.
Space saving POWR-GARD Class T fuses are the most compact fuses available in ratings above 30 amperes â less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of Class T fuses must be increased to prevent opening on inrush currents. In such instances, Class T fuses may provide only short circuit protection.
