Class J Fuses

Class J fuses are ideal for applications where space is limited.  These current limiting time-delay fuses may be small in size but offer high performance in order to provide time-delay to bypass motor or transformer surges.

  High performance with fatigue- free cycling capabilities Extremely current limiting

Applications:  Recommended for Type 2 (no damage) protection of IEC style motor starters and contactors. Use to protect lower interrupting rated circuit breakers. All general purpose circuits with inductive (high inrush) loads, including motor and motor branch circuits, and transformer circuits. Also suitable for lighting loads.
