It carries a 7 A ampacity maximum and accepts a 24 V DC supply (20.4 V min, 28.8 V max). Snaps onto a DIN rail (vertical or horizontal orientation accepted). The 30 mm width and 215 mm height fit standard 80 mm deep enclosures — the 75 mm depth leaves finger room behind the gland plate. Push-in terminals on both the main current circuit and the auxiliary/control circuit accept 1x 0.5 to 2.5 mm² solid or 18 to 10 AWG stranded. Use a 0.6 mm x 3.5 mm slot screwdriver to release the spring cage; no ferrule needed for solid wire. ## Environmental and electrical ratings Pollution degree 2 (non-conductive, occasional condensation). Shock resistance 6g at 11 ms; vibration resistance 15 mm at 6 Hz, 2g up to 500 Hz. Relative humidity 10 to 95 %. Between main and auxiliary circuits the insulation is rated 500 V.","metaTitle":"Siemens SIMATIC 3RK1908-0AP00-0CP0 BaseUnit, 7 A, 24 V DC","metaDescription":"SIMATIC 3RK1908-0AP00-0CP0 BaseUnit for AC feed-in. 7 A ampacity, 24 V DC, push-in terminals, DIN rail.
