The Siemens 3RV1917-5E is a broad extension connector designed to link 3-phase busbars of the 3RV1917-1/4 type, accommodating a wiring duct from 10 mm. It belongs to the SIRIUS 3RV1 family of motor starter protectors and accessories, used in control panels for motor branch circuits and feeder distribution.
The lifecycle stage is current, but the description flags this as a phased-out product. The preferred successor is the SIRIUS 3RV2 series part 3RV2917-5E. For BOM freeze or PCN watch, plan a transition to the 3RV2917-5E if you need long-term availability from the factory channel.
Integration Note
This connector mounts on the 3RV1917-1/4 busbar system inside a panel. The 10 mm wiring duct clearance means it fits standard DIN-rail enclosures; verify the duct height before laying out the panel. No special tools beyond a screwdriver are needed for the spring-cage or screw terminals on the busbar interface.
