Siemens UP UP361 Fusible Buss Plug

Siemens UV361 fusible bus plug is a three-pole, three-wire plug-in unit for ITE/Siemens Sentron busway systems. It is rated 30 A and 600 V and provides protective termination for a bus duct run with compatible Class R, H, and K fuses. This fusible plug belongs to the UV361 family and is used to extend or complete a busway installation in industrial environments, delivering protection for 3-phase circuits. The three-wire, three-pole configuration matches standard 3-phase distribution, and the fusible design allows for quick fuse replacement in the protection path. It is designed for compatibility with OEM ITE/Siemens XL-U Series industrial busway systems, and is listed as a fusible plug option in Siemens busway catalogs. When selecting bus plugs, engineers consider the 30 A/600 V rating and fuse compatibility to coordinate protection with upstream devices and downstream loads in a plant’s power distribution network.
