Integrator's note on the 3RT1015-2BB41-ZW96
The Siemens 3RT1015-2BB41-ZW96 is a SIRIUS power contactor in the S00 frame size, meaning it occupies a 45 mm width on the DIN rail and fits the standard 35 mm mounting rail per DIN EN 50022. Main circuit connections use spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or stranded wire, or 2x (24... 14) AWG. That's a straightforward termination for panel wiring — no screw torque to verify, just strip to the correct length and push in. The AC-4 rating at 400 V is 6.5 A — that's the inching or plugging duty cycle, lower than the AC-3 figure, so if the application involves frequent reversing or jogging, size on the AC-4 number. The AC-12 maximum operating current is 10 A for resistive loads.
Type 2 coordination (contactor remains operational after a fault) requires a 20 A gL/gG fuse. These are the manufacturer's specified values — don't substitute without verifying the let-through energy of the protective device.
