CEFCO OT 100 250 One Time Fuse

The Cefco OT 100 250 One Time Fuse is a single-use overcurrent protection device rated for 100 A at 250 V. It is designed to interrupt current when a fault or overload pushes the circuit beyond its nominal rating, protecting wiring and connected components from damage. The OT 100 250 model designation identifies the exact amperage and voltage rating for ordering and compatibility in electrical systems that require a 100 A, 250 V fuse. As a one-time fuse, it is intended for single-use protection; once it operates, the fuse must be replaced to restore circuit protection. Use of this fuse is appropriate in any application where a fixed 100 A, 250 V protection device is specified, and it should be integrated into the overall overcurrent protection strategy in accordance with applicable electrical standards.
