This isn't a resistive-load relay; it's sized for the contact wear a motor presents, so it holds up in a starter or coupling circuit. ## What the rating means in the panel The 3 kW / 400 V AC-3 figure governs the motor size this relay can handle directly. On a 400 V three-phase supply, that's roughly a 4 hp motor. The coupling relay sits between the control circuit and the motor contactor coil — it isolates the PLC or safety relay output from the coil draw, which is typically higher than a standard 24 VDC digital output can sink. If you're wiring this into a panel, the AC-3 rating tells you the main contacts are rated for the motor's starting current, not just the sealed current, so it won't weld shut on the first start.","metaTitle":"Siemens 3RT1015-1JB41-ZW95 Coupling Relay, AC-3, 3kW/400V","metaDescription":"Siemens 3RT1015-1JB41-ZW95 coupling relay, AC-3 rated for 3kW at 400V.
