Contactor, Size S00, 24 VDC Coil — SIRIUS 3RT2516-1BJ80
The Siemens 3RT2516-1BJ80 is a SIRIUS contactor in frame size S00, designed for switching motor loads and resistive loads in control panels. Its 24 VDC coil is controlled via screw-type terminals, and the main current circuit also terminates at screw-type terminals, making it a straightforward fit for standard panel wiring practices. Mounting is via screw and snap-on onto 35 mm DIN rail per DIN EN 50022, with side-by-side mounting permitted (zero spacing required upwards, forwards, backwards, and downwards; 6 mm clearance at the side). The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving panel builders flexibility in enclosure layout. Rated for operation from -25 to +60 °C and storage from -55 to +80 °C, this contactor suits environments from conditioned control rooms to unheated plant floors.
Integration and Compliance
Wire termination accepts solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), and 2x 4 mm². The screw-type terminals on both the coil and main circuit are compatible with standard ferrule and ring-tongue terminations used in panel building. The contactor's mechanical endurance is rated at 30,000,000 operating cycles typical, with a maximum switching frequency of 10,000 1/h at AC and 1,000 1/h at AC-1. Arcing time is 10...15 ms, with a DC dropout time of 7...13 ms — relevant for timing-critical interlock circuits.
