Power connection uses a HAN Q4/2 plug according to ISO 23570 — a standard industrial connector that mates quickly and keeps the enclosure seal intact. The unit also carries 4 digital inputs and 2 digital outputs, enough for local start/stop and a feedback signal back to the PLC without an extra I/O block. It mounts via screw fixing and can be installed vertically, horizontally, or flat, which helps when you're squeezing it into a tight corner of a machine frame or a wall-mounted enclosure. Vibration resistance is spec'd at 7 mm / 2g and shock at 12g / 11 ms, so it holds up on vibrating machinery like compressors or sorting shakers. The selectable trip class lets you dial in the overload protection without swapping heater packs — a single part covers a range of motor FLCs. Supply voltage is 24 V DC nominal (20.4 to 28.8 V range), so it runs off a standard control transformer or industrial power supply. The digital inputs are 24 V DC as well, keeping the control wiring consistent across the panel.","metaTitle":"Siemens 3RK1395-6LS71-0AD3 SIRIUS Motor Starter, IP65, 5.5 k","metaDescription":"Siemens 3RK1395-6LS71-0AD3 SIRIUS direct motor starter.
