Ferraz Shawmut OTS40 Low Voltage Fast Acting Fuse, 40 A, 600 VAC, 300 VDC, 50/20 kA, K5 K5, Cylindrical Body

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 50000 A 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.
