Communication is over AS-Interface (the AS-Interface protocol is confirmed), with device addressing via an M12 plug. Four digital inputs are onboard for local limit switches or pushbuttons, and the main power circuit connects via a HAN Q4/2 plug conforming to ISO 23570. ## Ratings that drive the selection decision The 24 V DC supply (20.4 to 28.8 V range, max permissible 31.6 V, min permissible 26.5 V) powers the AS-Interface bus and the starter's logic. The 85 ms ON-delay and 65 ms OFF-delay are fixed — not adjustable — so factor those into your sequence timing if the starter is part of a safety-related interlock chain. Trip class is selectable among CLASS 5, 10, 15, and 20 — that's the maximum time in seconds the overload relay allows before tripping under a locked-rotor condition. Class 10 is the standard for general-purpose motor starting; Class 20 buys you headroom for high-inertia loads like fans or centrifuges. The starter does not support direct start (only reversing), but it does support reverse starting. Mounting is flexible — vertical, horizontal, or flat — though the recommended orientation is horizontal. Screw fixing is the fastening method. The unit measures 294 mm wide, 215 mm high, and 159 mm deep, so check that your enclosure or machine frame has clearance for the width, especially if ganging multiple starters side by side. ## Environmental and lifecycle posture The IP65 enclosure is the first line of defence, but the internal clearance and creepage distances are designed for Pollution Degree 3.","metaTitle":"Siemens 3RK1325-6LS41-1AA3 SIRIUS Reversing Starter, IP65, 5","metaDescription":"Siemens SIRIUS 3RK1325-6LS41-1AA3 reversing motor starter.
