One-Time OTS general purpose fuses provide low cost protection for feeder and branch-circuits serving lighting, heating, and other non-motor loads. OTS fuses will safely interrupt available short circuit currents up to 50,000 amperes in all ratings. OTS fuses are not rejection fuses and care should be taken to ensure that replacement fuses do not have lower interrupting ratings than original fuses.
