It includes PE and neutral conductor connection. This is the mechanical and power-distribution backbone for an AS-i load feeder station — it carries the busbar adapter and provides the connection point for the load feeder module's power supply. A critical sourcing note: the 3RK1901-0EA power connector set is required separately and is not included with this support. Verify that connector set is on the same BOM line or order it alongside this adapter. The 54 mm width matches the standard footprint for SIRIUS AS-Interface load feeder modules. Mounting is on a busbar with 60 mm center-line spacing — this is the standard 60 mm busbar pitch common in Siemens AS-i panels. The PE and neutral conductor connection is built into the adapter, so no separate terminal block is needed for the protective earth and neutral feed to the load feeder. This support is the mechanical interface between the busbar and the load feeder module. It does not contain electronics — it is the carrier and power-distribution adapter. The actual load switching and AS-i communication happen in the load feeder module that mounts onto this support. The paperwork — RoHS, REACH, CE, and manufacturer declarations — is standard with Siemens SIRIUS components and is provided with the shipment.","metaTitle":"Siemens 3RK1901-3DA00 AS-Interface Support, 54 mm, Busbar Mo","metaDescription":"Siemens 3RK1901-3DA00 AS-Interface support for load feeder module, 54 mm wide, PE/neutral connection, 60 mm busbar spacing.
