Siemens 3RV1915-5B Three-Phase Feed-In Terminal

Siemens 3RV1915-5B is a 3-phase feed-in terminal block designed to bring three-phase power from the busbar into S0/S00 sized motor starters in control cabinets. It provides bottom-entry, screw-type connections for the main current circuit and is rated for up to 63 A with an insulation voltage of 690 V, making it suitable for standard industrial feeder duties. The enclosure measures 44 mm wide, 73 mm high and 48 mm deep, and the front is rated IP20, which helps guard the terminals from incidental contact while the device is installed in a cabinet. Operational temperature range is -20 to +60 C, aligning with typical factory environments. This terminal serves as the fixed feed-in point in three-phase circuits, consolidating wiring at the starter interface and enabling clean, reliable distribution from the three-phase supply to the motor starter assembly. The 3RV1915-5B is commonly listed by Siemens distributors as a 3-phase feed-in terminal block for S0/S00 motor starters and is designed for screw-terminal connections with bottom-busbar entry.
