The Siemens 3RK1901-3AA00 is a 45 mm wide AS-Interface support designed for a load feeder module, intended for mounting on a busbar with 40 mm center-line spacing. It includes PE and neutral conductor connection, so it handles the power distribution and grounding for the feeder module in one assembly. Note that a 3RK1901-0EA power connector set is required separately — that part is not included with this support.
