It operates on a 24 V DC control supply and offers selectable trip classes 5, 10, 15, and 20, giving you flexibility to match motor protection to the load — fast trip for pumps, slower for high-inertia conveyors. This is a reversing starter, meaning it can switch a three-phase motor in both forward and reverse directions without external contactor interlocking. It includes four digital inputs and two digital outputs for control and feedback, and connects to the main circuit via a HAN Q4/2 plug conforming to ISO 23570. ## Mounting and environmental considerations The enclosure measures 294 mm wide, 215 mm high, and 148 mm deep, and is fixed by screw fixing. It can be mounted vertically, horizontally, or flat, giving you options for tight panel layouts or machine-mounted installations. It withstands vibration of 7 mm / 2g and shock of 12g / 11 ms, so it holds up on machine frames or near rotating equipment.","metaTitle":"Siemens 3RK1395-6KS71-3AD0 SIRIUS Reversing Starter, IP65, 0","metaDescription":"Siemens SIRIUS 3RK1395-6KS71-3AD0 reversing motor starter.
