It's a self-contained motor starting solution: you bring 24 V DC control power and a motor supply, and it handles the rest. This is a direct-on-line (DOL) starter — no reversing, no soft-start, just a straightforward across-the-line start. It's rated to switch a 0.75 kW motor at 400 V AC, pulling 2 A in that duty. The 24 V DC control supply powers the onboard logic and the 4 digital inputs and 2 digital outputs, so you can wire in start/stop pushbuttons, limit switches, or a PLC's dry-contact outputs directly. The trip class is selectable between CLASS 5, 10, 15, and 20 — that's the maximum time in seconds the overload relay will allow before tripping at a locked-rotor condition. For a pump or fan with a long acceleration curve, set it to CLASS 20 so you don't nuisance-trip during start-up. For a fast-cycling conveyor, CLASS 5 gives tighter motor protection. The main power circuit connects via a HAN Q4/2 plug (per ISO 23570), which is a common industrial rectangular connector — you'll need the mating half on your motor cable. The 4 digital inputs and 2 digital outputs are on-board; no separate I/O module required for basic start/stop and feedback. It's rated for vertical, horizontal, or flat mounting, and the recommended orientation is horizontal. With an IP65 enclosure, you can mount it outdoors or in washdown areas, but keep the ambient temperature between -25 °C and +55 °C during operation. The screw-fixing method means you bolt it to a machine frame or a sub-panel — no DIN rail required.","metaTitle":"Siemens 3RK1395-6KS71-0AD0 SIRIUS Motor Starter, IP65, 2 A a","metaDescription":"Siemens SIRIUS 3RK1395-6KS71-0AD0 direct motor starter.
