Three normally open main contacts handle the load; the magnet coil draws 3.3 W both closing and holding. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire. Side-by-side mounting is supported with a 6 mm gap to the side. Panel depth allowance: 114 mm. The 5.5 kW AC-3 rating at 400 V covers standard squirrel-cage motor switching — that's the load a contactor this size typically sees. The 24 VDC coil holds at 3.3 W; verify the control transformer or power supply can deliver that continuously. The 10 A AC-12 rating covers resistive loads like heaters.","metaTitle":"Siemens 3RT1017-2BB44-3MA0 SIRIUS Power Contactor, 24 VDC, 5","metaDescription":"Siemens SIRIUS 3RT1017-2BB44-3MA0 power contactor, size S00, 24 VDC coil, 5.5 kW at 400 V AC-3.
