Siemens 3RV2917-1A Busbar

Siemens 3RV2917-1A is a 3-phase busbar from the SIRIUS 3RV29 family, designed with a left-side infeed for two circuit breakers (sizes S00 and S0) and intended to accompany Siemens 3RV2 breakers in a compact, modular input section. The three-pole main current path carries a rated current of 63 A and a rated AC voltage of 500 V (UL/CSA ratings up to 600 V), with a surge-withstand rating of 6 kV, and heat loss of 4.52 W per pole at rated current. Weighing about 0.417 kg, the unit measures roughly 129 mm wide and 110 mm deep and is front-protected to IP00, with IP20 possible when using finely stranded conductor of 6 mm² with an end sleeve. It carries CE, UL, CSA and CCC certifications and is designed for use within the Sirius modular system to form a robust busbar assembly feeding two 3RV2 breakers in a 3-pole configuration.
