Siemens 3RT2015-1BB41-0CC0 SIRIUS Power Contactor, 24 VDC Co

The 3RT2015-1BB41-0CC0: The 24 VDC coil (rated value 24 V) draws an initial inrush of 0.8 A and holds at a lower sealed current — critical for sizing your 24 VDC power supply and verifying the PLC output card can drive the coil without a separate interposing relay. The main contacts are rated for AC-1 resistive loads at up to 1,000 switching cycles per hour, AC-3 motor loads at 750 cycles/hour, and AC-4 (plugging/reversing) at 250 cycles/hour. For AC-3e (high-efficiency motor) duty, the maximum is also 750 cycles/hour. These frequency limits govern how often the contactor can be cycled without exceeding thermal rise — a key parameter for high-speed indexing or jogging applications. The auxiliary switch (included) is rated for switching at various DC voltages: 10 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, and 3 A at 400 V. These DC ratings are inductive load limits — use them to confirm the auxiliary contacts can handle your PLC input or pilot lamp loads without welding. Terminals accept solid or stranded wire: 0.5 to 4 mm² for main conductors, and 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² for auxiliary circuits. The screw-type terminals are field-proven for vibration resistance in industrial environments.
