Main circuit termination uses spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded wire. That means no screw-torque checks on the line — just strip to 8 mm and push in. The mounting position is flexible: vertical surface with +/-180° rotation, or +/-30° tilt front-to-back. That covers most panel layouts — upright, rotated 90°, or tilted in a sloped enclosure. Dimensions are 45 mm wide, 60 mm high, 72 mm deep. At 45 mm, it occupies a single 45 mm DIN-rail module width — standard for size S00 contactors.","metaTitle":"Siemens 3RT1516-2BP40 SIRIUS Power Contactor, 10 A at 24 VDC","metaDescription":"Siemens SIRIUS 3RT1516-2BP40 power contactor, size S00, 10 A at 24 VDC coil, spring-loaded terminals, DIN rail mount.

The 3RT1516-2BP40 uses spring-loaded terminals, while the 3RT1016-2AP02 may use screw terminals — the wire entry points are in the same locations, but you will need to confirm the terminal type matches your existing wiring method.
