For a 24 VDC solenoid or small motor brake, the 10 A rating gives comfortable headroom. At 230 V AC the contactor is rated 10 A, and at 400 V AC it's 3 A — these AC ratings follow the same pattern but with higher currents because the arc self-extinguishes at the zero crossing. ## Panel fit and mounting flexibility Clearance requirements are tight: zero mm spacing upwards, forwards, and backwards, with only 6 mm needed at the sides for heat dissipation. That means you can pack these contactors side-by-side without derating. ## Terminals and wiring Both the main current circuit and the coil use screw-type terminals — standard for industrial panels where ring lugs or ferrules are the norm. An auxiliary switch is built in, saving a separate add-on block for basic feedback or status signalling.","metaTitle":"Siemens 3RT2517-1BE40 SIRIUS Contactor, S00, 24 V DC Coil","metaDescription":"Siemens 3RT2517-1BE40 SIRIUS contactor, size S00, 24 V DC coil, rated 10 A at 24 V DC.
