Siemens 8US10615FK08 Busbar Adapter

Siemens 8US10615FK08 Busbar Adapter is a device adapter for the Siemens 8US busbar system (60 mm width), designed to provide a mounting interface for modular protective devices on a busbar assembly. Part of the 8US1 family, it enables secure integration of devices such as circuit breakers and fuse blocks into low-voltage distribution gear using the 60 mm busbar spacing. Typical applications include Siemens switchgear, distribution boards, and control panels where compact, modular device mounting on 8US busbars is required; the part number corresponds to the 8US1 061-5FK08 configuration. Some distributors list the 8US1 adapters for mounting 2-pole and 3-pole fuse blocks on 60 mm busbars, illustrating its role in mixed-device configurations within the 8US busbar ecosystem.
