SIRIUS S10 Power Contactor, 23-26 VDC Coil
The coil is rated for a 23-26 VDC pickup range, with a 1.1x full-scale value and an initial pickup threshold of 0.8x rated voltage — per the datasheet, that means it pulls in reliably at about 18.4 VDC and holds across the nominal band. Mounting is via screw fixing with four 11 mm holes on a vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back. The main power terminals accept stranded cable from 70 to 240 mm²; the coil connection uses spring-type terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded. That spring cage on the coil side saves panel-builder time — no screw torque to verify, just strip to 8 mm and insert. Dimensions are 202 mm deep, 145 mm wide, 210 mm tall.
The contactor carries an auxiliary switch rated at 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. The main contact switching frequency varies by duty class: 750 operations per hour maximum at AC-1 (resistive), 250/h at AC-2 (slip-ring motors), 500/h at AC-3 (squirrel-cage motors), and 130/h at AC-4 (plugging/inching). The AC-3e rating matches the AC-3 figure at 500/h. The power factor at 50 Hz and 60 Hz is 0.9. The mechanical life of the contactor is typically 10,000,000 operations.
