The trip class is field-selectable among CLASS 5, 10, 15, and 20 — that means you match the overload protection to the motor's start-up profile: fast tripping for short acceleration times (CLASS 5), or a longer window for high-inertia loads like fans or centrifuges (CLASS 20). The unit is a direct starter (no reversing), so it's a straightforward on/off control for a single-direction motor. It carries an IP65 enclosure, meaning the housing and the HAN Q4/2 power connector are sealed against dust and low-pressure water jets — suitable for washdown areas or outdoor cabinets where a standard open starter would need a separate enclosure. The supply voltage is 24 V DC (20.4 to 28.8 V range), so it drops into a standard 24 V control circuit without a separate power supply. The starter includes 4 digital inputs and 2 digital outputs, letting you wire start/stop pushbuttons, limit switches, or a PLC directly without an extra I/O block. The ON-delay is 25 ms and the OFF-delay is 35 ms — these are the response times of the internal logic, not the contactor dropout, so they matter when sequencing multiple starters in a timed cascade. ## Mounting, environment, and panel integration The starter measures 294 mm wide, 215 mm high, and 148 mm deep. The recommended mounting position is horizontal, but it also works vertical or flat — the orientation affects heat dissipation, so if you mount it vertical, check that the ambient stays within the -25 to +55 °C operating range. Vibration resistance is 7 mm at 2g, shock resistance is 12g for 11 ms — typical for a machine-mounted starter on a conveyor or pump skid.","metaTitle":"Siemens 3RK1395-6KS71-2AD0 SIRIUS Motor Starter, IP65, 0.75","metaDescription":"Siemens SIRIUS 3RK1395-6KS71-2AD0 direct motor starter, 0.75 kW at 400 V, IP65, trip classes 5–20, 4 DI/2 DO, 24 V DC.
