It includes provisions for PE and neutral conductor connection, so it handles the protective earth and neutral distribution for the feeder module it carries. This is the mechanical and electrical backbone that positions the load feeder on the busbar and ties it into the AS-Interface network. One critical detail: the 3RK1901-3CA00 requires the 3RK1901-0EA power connector set to function. If you're sourcing this for a new build or a replacement, make sure that connector set is on the BOM — the support bracket itself does not include the power tap. At 45 mm wide, the 3RK1901-3CA00 occupies a single standard busbar slot on a 60 mm center-line rail. It supports the AS-Interface load feeder module — think of it as the mounting cradle that also carries the network and power distribution for that module.","metaTitle":"Siemens 3RK1901-3CA00 AS-Interface Support, 45mm, Busbar Mou","metaDescription":"Siemens 3RK1901-3CA00 AS-Interface support for load feeder module, 45mm wide, for 60mm busbar with PE/neutral connection.
