Approvals & Standards

  • UL Listed to Standard 248-9 File E2137
  • CSA Certified to Standard C22.2 No. 248.9 (The Canadian Electrical Code requires these fuses in ratings 15 through 60A to be of the low melting point design; use OTN 15-60.)
  • Self-certified for DC per UL248

Key features & benefits

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.
