Mersen OT200
Fuse 250V 200A Fast-Acting Class K5 OT Series
Product Description
The OT and OTN series fuses are designed for low-cost protection of feeder and branch circuits, primarily serving lighting, heating, and non-motor loads. These fuses can safely interrupt available short-circuit currents up to 50,000 amperes across all ratings, ensuring reliable performance in various applications. It is crucial to replace these fuses with equivalents that meet or exceed the original interrupting ratings to maintain safety standards.
The OTN(15-60) variant complies with the Canadian electrical code requirement for Type P low melting-point, non-time-delay fuses, making it suitable for specific regulatory environments. The fuse features a fast-acting characteristic, ensuring immediate response to overcurrent conditions.
Constructed with a body made of PolyTube and using tin-plated copper for the connection terminals, this fuse is both effective and durable. It has a compact design with a diameter of 1.56 inches and a length of 7.13 inches, weighing 0.765 lb, facilitating easy installation in various systems.
