It's rated 12 A at 400 V AC (5.5 kW) and carries a 7.5 hp rating at 460/480 V, so it handles typical three-phase induction motors in the 5–7.5 hp range on 400–480 V line supplies. ## Trip class flexibility and control voltage The overload relay section is adjustable across Trip Classes 5, 10, 15, and 20. That range covers fast-acting protection for short-stall motors (Class 5) up to slower-trip applications like high-inertia loads (Class 20). The control circuit runs on 24 V DC (20.4–28.8 V range), which is standard for modern PLC-controlled panels and keeps the control voltage SELV-compatible. Four digital inputs and two digital outputs are onboard for direct connection to a controller — no separate I/O block for basic start/stop and status feedback. The starter measures 294 mm wide by 215 mm tall by 148 mm deep and uses screw fixing — no DIN rail clip, so plan for drilled mounting holes in the backplate. It can be mounted vertically, horizontally, or flat, but the evidence recommends horizontal orientation for best thermal performance. Operating temperature range is -25 to +55 °C, and it's rated for shock resistance of 12g at 11 ms and vibration resistance of 7 mm / 2g — tough enough for machine-mounted applications near rotating equipment. The main power connection uses a HAN Q4/2 plug per ISO 23570, so the mating connector needs to be ordered separately if not already on hand.","metaTitle":"Siemens 3RK1395-6LS71-1AD0 SIRIUS Reversing Starter, 12A, IP","metaDescription":"Siemens SIRIUS 3RK1395-6LS71-1AD0 reversing motor starter. 12 A at 400 V AC, 5.5 kW, IP65 enclosure.
