It ships with an integrated auxiliary switch, so you don't need a separate side-mount block for basic status feedback or interlocking — one less part to stock and one less terminal to wire. The coil is rated at 110 V AC, a standard control voltage in many industrial installations, with a pickup threshold of 0.8 x rated value and a dropout of 1.1 x full-scale value. ## Auxiliary contact ratings across the voltage range At 110 V AC — the coil voltage of this contactor — the auxiliary contacts carry 1 A, so confirm the downstream load current stays under that limit if you're using the same supply rail for both coil and feedback. ## Mounting flexibility and panel clearances Zero clearance is required upwards, forwards, backwards, and downwards (–), so you can butt it against other devices on the rail without derating. Only 6 mm side clearance is needed for heat dissipation. ## Termination and wiring capacity Both the main current circuit and the magnet coil use screw-type terminals — a field-serviceable choice that doesn't require special crimp tools.","metaTitle":"Siemens 3RT2517-1BF40 SIRIUS Contactor, Size S00, 110 V Coil","metaDescription":"Siemens 3RT2517-1BF40 SIRIUS contactor, size S00, 110 V AC coil, screw terminals.
