Littelfuse 0JTD090.V Time-Delay Fuse 90A 600V

The Littelfuse 0JTD090.V 600V, 90A Time-Delay Fuse is used to protect electrical circuits against overcurrent conditions in HVAC systems. It permits small temporary currents those produced by motor starting and rapidly breaks off dangerous short circuits. This time-delay feature reduces the number of nuisance trips, enhancing the system’s dependability. Such fuses are appropriate in the chillers, the rooftop units, and large air handlers where the motor starting currents are high. They improve system availability by preventing equipment damage and safe operation thereby lowering maintenance expenses.
