One-Time OT general purpose fuses provide low cost protection for feeder and branch circuits serving lighting, heating and other non-motor loads. OT fuses will safely interrupt available short circuit currents up to 50000 amperes in all ratings. OT fuses are not rejection fuses - care should be taken to ensure that replacement fuses do not have lower interrupting ratings than original fuses.
