The magnet coil uses spring-type terminals — no screwdriver needed for the coil connection, which speeds up panel wiring. Main contact terminals accept solid or stranded wire from 0.5 to 4 mm², and can take two conductors per terminal (2x 0.5 to 4 mm²). ## Duty ratings and switching frequency This contactor is rated for AC-1 (resistive), AC-2, AC-3, and AC-4 duty classes, with maximum switching frequencies: 1000 operations/hour at AC-1, 750/h at AC-2 and AC-3, and 250/h at AC-4. The AC-3e rating also caps at 750/h. These limits govern how fast you can cycle the contactor in motor-starting or resistive-load applications — exceeding them shortens life or causes weld risk. Switching capacity at DC voltages: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.14 A at 440 V. For DC loads, the arcing time is 4 to 15 ms at AC, and the contactor is rated for 0.25 A holding current at 50/60 Hz. Motor horsepower rating at 230 V is 0.75 hp — useful for small pump or fan motors in the sub-1 hp range. Typical mechanical endurance is 10 million operations — a high-cycle figure that suits frequent switching in conveyor or packaging lines.","metaTitle":"Siemens 3RT2015-2CP04-3MA0 SIRIUS Power Contactor, Size S00,","metaDescription":"Siemens SIRIUS 3RT2015-2CP04-3MA0 power contactor, Size S00, 45 mm width, spring-type terminals, screw and snap-on DIN rail mount.
