Bussmann 200A-600V-OTF One Time Fuse

Bussmann NOS-200 One-Time Fuse is a high-current, single-use cartridge fuse rated for 200 A and up to 600 V, designed for general-purpose overcurrent protection in industrial power-distribution systems. The NOS-200 fuse is a cartridge-type device that requires a compatible Bussmann fuse holder for installation in panels, disconnects, or equipment where a one-time protection element is specified. With an approximate diameter of 1.84 inches and a length of 9.63 inches, this fuse occupies a substantial footprint in larger electrical assemblies. It carries a 200 A amperage rating and a 600 VAC voltage rating, making it suitable for protecting feeders and large loads in commercial or industrial installations. Classified as a one-time fuse within the Bussmann line (part of Eaton Bussmann), NOS-200 is marketed as a general-purpose fuse rather than a fast-acting or time-delay device. Typical applications involve protection in industrial control panels, fuse blocks, and power-distribution equipment where a single-use protective device is appropriate and replacement is anticipated after a fault event. For correct replacement, pair the NOS-200 with the appropriate Bussmann holder designed for NOS fuses, and observe system voltage, current, and fault-current requirements to ensure safe and compliant operation.
