Key Ratings and What They Mean for Your Panel
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. The contactor's footprint is 45 mm wide, 58 mm high, and 73 mm deep, fitting standard Size S00 panel layouts. Clearance requirements: 10 mm upwards and forwards, 10 mm downwards, and 6 mm at the sides. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward — useful for tight enclosures or angled subpanels. 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.
