SIRIUS S00 power contactor — 4 NO, 24 VDC coil
The Siemens 3RT1316-1AP60 is a SIRIUS S00-frame power contactor with four normally-open main contacts and a 24 VDC coil. It switches motor loads up to 4 kW at 400 V in AC-2 duty (slip-ring motors, wound-rotor) and handles resistive loads up to 10 A in DC-12. The S00 frame keeps the width at 45 mm, depth at 72 mm, and height at 57.5 mm — fits standard 35 mm DIN rail per EN 50022 with screw or snap-on mounting.
The DC-12 rating (10 A at 24 V) covers resistive DC loads like solenoids or brake coils.
Side-by-side mounting is allowed (no derating gap required), but the front face is IP20, so keep it behind a panel door or enclosure.
