It is rated for a motor power of 0.75 kW at 400 V AC and carries a rated operational current of 2 A at 400 V AC, making it suitable for small induction motors driving pumps, fans, or conveyors. The unit is also rated at 0.7 hp at 460/480 V and 1 hp at 575/600 V, covering common North American voltage levels. The starter offers selectable trip classes (CLASS 5, 10, 15, 20), allowing the overload protection curve to be matched to the motor's starting characteristics — a Class 10 setting for short acceleration times, Class 20 for high-inertia loads. This flexibility is critical for protecting the motor without nuisance tripping during startup. The enclosure is designed for screw fixing and can be mounted vertically, horizontally, or flat, giving panel builders layout flexibility. ## Electrical and Control Interface The starter is powered by a 24 V DC control supply, with a permissible range of 20.4 to 28.8 V DC. This is a standard industrial voltage, compatible with most PLC and control system outputs. The unit provides 4 digital inputs and 2 digital outputs for integration into a control circuit, allowing remote start/stop and status feedback without additional I/O modules. The main circuit connection uses a plug according to ISO 23570 (HAN Q4/2), a standardized industrial connector that simplifies wiring and replacement. The unit does not support PROFINET, PROFIBUS DP, or AS-Interface protocols — control is via hardwired digital signals only. On-delay time is 85 ms and off-delay time is 65 ms, providing predictable switching behavior for sequencing logic. The starter supports direct start only; reverse starting is not available, so a separate reversing contactor is required for bidirectional motor control. It withstands shock loads of 12g for 11 ms and vibration of 7 mm at 2g, per the datasheet, making it robust for installation on machinery or in mobile equipment. This is typical for control panels in factory floors or process plants. Physical dimensions: 294 mm width, 215 mm height, 148 mm depth. The recommended mounting orientation is horizontal, though vertical and flat positions are also permitted. The unit is not designed for on-site operation — it is intended for remote control via the digital inputs. The unit is not a direct cross-reference for the 3RT5065-6NF36 or 3RT1044-1FB46 — those are contactors, not integrated motor starters with overload protection and I/O.","metaTitle":"Siemens 3RK1395-6KS41-0AD3 SIRIUS Motor Starter, 2 A at 400","metaDescription":"Siemens 3RK1395-6KS41-0AD3 SIRIUS direct motor starter, rated 2 A at 400 V AC, 0.75 kW.
