The Siemens 3RV29255AB is a three-phase supply terminal, part of the SIRIUS product line, designed for direct busbar connection from the top. This accessory is specifically engineered for use with Siemens Size S00 and S0 circuit breakers, providing a robust connection point.
Key electrical specifications include a maximum ampacity of 63A and an insulation voltage rating of 690V with a degree of pollution 3. The terminal features screw-type connections for the main current circuit, accommodating solid conductors from 2.5 to 16 mm², stranded conductors from 2.5 to 25 mm², and finely stranded conductors with core end processing from 2.5 to 16 mm². It also supports AWG cables from 10 to 4.
Mechanically, the terminal has a width of 44.5mm, a height of 39mm, and a depth of 27.2mm. It offers IP20 protection on the front, meeting IEC 60529 standards, and provides finger-safe touch protection for vertical contact from the front. The operating ambient temperature range is -20°C to +60°C, while storage temperatures can range from -50°C to +80°C.
This component holds certifications including CE, UL, CSA, and CCC, indicating broad compliance for various industrial applications. The 3RV29255AB serves as a critical interface for three-phase power distribution within control panels and electrical systems.
