It is purpose-built for the ET 200x EM 300 distributed I/O family and the AS-i compact starter range — not a generic patch cable. The 9-pole interface matches the power tap on those modules, so you are wiring the motor or actuator supply through a single pre-assembled harness rather than landing individual conductors at the module terminals. The substance prohibitance date of 05/01/2012 confirms RoHS compliance. ## What the 9-pole 4 mm² rating means in practice The 4 mm² cross-section per conductor supports the full rated current of the ET 200x EM 300 power module or AS-i compact starter without voltage drop over the 0.12 m run. That short length (barely longer than a hand span) is intentional — it keeps the cable routed tight to the module face, avoiding loop inductance and mechanical snag points inside the panel. The 9-pole connector carries both the DC supply and the AS-i data pair in one shell, so a single plug-in connection replaces what would otherwise be separate power terminals and an AS-i tap. If you are replacing a damaged cable, verify the connector keying matches your module generation; the 9-pole interface is mechanically coded.","metaTitle":"Siemens 3RK1902-0CG00 Power Connection Cable, 4x4 mm², 0.12","metaDescription":"Siemens 3RK1902-0CG00 power connection cable for ET 200x EM 300 and AS-i compact starter. 4x4 mm², 0.12 m, 9-pole.
