It serves as the mechanical and electrical backbone for a 3-pole main current circuit, using push-in terminals for wiring. The 75 mm depth is a critical dimension for panel layout — it tells you how much clearance the unit needs from the DIN rail to the enclosure door or back wall. The 7 A ampacity maximum governs the total current you can run through the main circuit; if your load pulls more than that, you need a different base unit. The 24 V DC supply is the control voltage that powers the module's internal logic. The vibration resistance of 15 mm to 6 Hz and 2g to 500 Hz, plus shock resistance of 6g / 11 ms, tells you it can handle the shake on a motor control center or conveyor line. The push-in terminals accept 0.5 to 2.5 mm² solid or finely stranded wire with core end processing — no screwdriver needed for the wire entry, though a 0.6 mm x 3.5 mm slot screwdriver is used for release. It's a clean, fast wiring setup for panel builders. The unit carries a substance prohibitance date of April 15, 2016. Pollution degree 2 rating means it's suitable for normal industrial environments with only non-conductive pollution.","metaTitle":"Siemens 3RK1908-0AP00-0DH0 SIMATIC BaseUnit, 3-pole, 7 A, 24","metaDescription":"Siemens 3RK1908-0AP00-0DH0 SIMATIC BaseUnit, 3-pole main circuit, 7 A max, 24 V DC supply, 75 mm depth, push-in terminals, DIN-rail mount.
