The IP65 enclosure means this unit is suited for washdown environments or outdoor installation without a separate cabinet — the screw-fixed housing seals the power and control electronics against dust and low-pressure water jets. Trip Class selection covers CLASS 5, 10, 15, and 20, so the overload protection curve can be matched to the motor's starting profile — CLASS 10 for standard induction motors, CLASS 20 for high-inertia loads like fans or centrifuges. Four digital inputs and two digital outputs are integrated, reducing the need for separate I/O modules in the control circuit. The reversing function is built in, so no external contactor interlock is required for direction change. Dimensions are 294 mm wide, 148 mm deep, 215 mm high. Mounting is by screw fixing; the unit can be installed vertically, horizontally, or flat. Horizontal orientation is recommended for optimal thermal performance. The main circuit connects via a HAN Q4/2 plug per ISO 23570, so panel wiring uses a pre-terminated harness rather than direct cable entry. Vibration resistance is 7 mm / 2g; shock resistance is 12g for 11 ms. ## Control and timing characteristics Rated control supply voltage is 20.4 to 28.8 V DC. ON-delay is 85 ms; OFF-delay is 65 ms. The unit supports reverse starting but not direct on-line starting — the reversing contactor pair handles direction change internally.","metaTitle":"Siemens 3RK1395-6LS41-1AD0 SIRIUS Reversing Starter, 5.5 kW","metaDescription":"Siemens SIRIUS 3RK1395-6LS41-1AD0 reversing motor starter, 5.5 kW at 400 V, IP65, Trip Class 5-20, 4 DI/2 DO.
