1.4 250TPA08 Overview The Amphenol Network Solutions 250TPA08 family of 1RU, dual-feed 250A per feed, power distribution panels provide high-capacity, ±48V, ±24V, and ±12V power protection for secondary power distribution to data and communications equipment. The Amphenol Network Solutions 250TPA08 family panels are also ideal for primary distribution in small central offices and at remote sites.
Fig. 1-4: 250TPA08-C-16F Rear View This panel accommodates Cooper Bussmann TPA fuses. As an optional accessory, AIRPAX 1U circuit breakers can be used as an alternate to TPA fuses. The panel has positions for 16 bullet-style, plug-in fuse holders or breakers. These 1RU fuse holders feature an ergonomic front grip for easy removal, sliding top cover to protect the fuse from above, and red alarm plunger to indicate a failed fuse.
