3RT2025-2BB44
S00 chassis 3-pole AC contactor, AC-3 17A/7.5kW, 24V DC coil with spring terminals and 2NO+2NC auxiliary contacts, suitable for panel wiring requiring multiple interlocking signals.
The 3RT2025-2BB44 is the smallest standard AC contactor (S00 frame) in the SIRIUS 3RT2 series. Its main circuit can handle 17A under AC-3 conditions, equivalent to a 7.5kW motor load at 400V, and up to 11kW/13A at 690V. This model uses a 24V DC operating coil and has four auxiliary contacts (2NO + 2NC), double the number of auxiliary contacts in the basic model of the same series. It is particularly suitable for control circuits that require simultaneous feedback of both "started" and "stopped" states, or those requiring multiple safety interlocks. Both the main and auxiliary circuits use spring-loaded (screwless) terminals. During field wiring, simply pressing down the spring clips secures the wires, reducing the time spent on repetitive wiring and minimizing the risk of poor contact due to loose screws after long-term use. It complies with international standards such as IEC and UL/CSA, and is suitable as the main contactor for small to medium-sized three-phase motors such as conveyors, pumps, and windmills, or for use in conjunction with reversible contactor groups.
