Product details

The Siemens 3RT2024-2BB40-0CC0 is a SIRIUS power contactor in Size S0, designed for switching DC loads up to 10 A at 24 V (DC-13 duty).

The 10 A DC-13 rating at 24 V means this contactor is suited for switching inductive DC loads like solenoid valves, relays, and small DC motors in control panels. The spring-type terminals accept solid or stranded conductors from 1 to 10 mm², or 2x (0.5 to 2.5 mm²) for daisy-chaining. The coil holds at 24 VDC nominal, with a pick-up threshold of 0.8 x rated value (19.2 V), and drops out below that.
