The Siemens SIRIUS 3RK1395-6KS71-3AD3-ZE07 is an M200D reversing motor starter — a special variant built to SEAT/VW specifications with a key-operated switch and CES technology module. It switches motor loads electronically using solid-state thyristors on two phases, rated at 2 A in AC-3 duty at 400 V, which means it handles small reversing motor applications up to roughly 0.75 kW. The 24 V DC control supply (20.4... 28.8 V range) powers the electronics, drawing 600 mA during operation and 100 mA in standby.
Lifecycle reality — NRND and what that means for procurement
This order code carries an NRND (Not Recommended for New Designs) lifecycle status. For an OEM with this part on the BOM, that means the manufacturer is signaling end-of-life intent — no new design-ins, and the supply window for production builds is finite.
The solid-state design (thyristor, two-phase switching) means no mechanical contact wear, but also means leakage current and heat dissipation to account for in the enclosure. Electronic overload protection is built in, with a thermistor (THERMOCLICK / PTC) input for motor temperature monitoring. The supply voltage range of 20.4... 28.8 V DC is tight enough that a sagging 24 V bus below 20.4 V will drop the unit out.
Integration and connectivity
This reversing starter includes 4 digital inputs and 2 digital outputs, plus a brake contact rated at 400 V AC. Communication is handled through a separate 3RK1305* module, making it usable on PROFIBUS or PROFINET networks. The Han Q4/2 and Han Q8/0 connectors provide the motor and I/O interface. Manual on-site operation and a key-operated switch are integrated, which suits applications where local lockout or operator control is required.
