Product Positioning

The SIRIUS 3RT2024-2FB40 is a Siemens S0 frame contactor with an AC-3 rated current of 12A and an output of 5.5kW at 400V. The coil is rated for 24V DC, and the terminals feature a spring-loaded (screwless) design, allowing for quick insertion and removal of wires simply by pressing down the spring. The auxiliary contacts are 1NO + 1NC and meet the specifications for reversible switching interlocking applications, making it suitable for use with another contactor to form a forward/reverse circuit. Kenxin Motors provides genuine Siemens parts and selection consultation services.

Core Product Advantages and Features
Spring-loaded terminal quick wiring
Both the main circuit and the control circuit use spring clip terminals, which can complete the wiring without the need for screwdrivers, making it particularly suitable for shortening the assembly time when mass-producing distribution panels.
24V DC coil
The coil is rated at 24V DC, making it suitable for use with PLCs or automation systems powered by a 24V DC control power supply. The signal switching is clean and free of AC noise.
1NO+1NC reversible auxiliary contact
The auxiliary contact specifications are specifically designed for forward and reverse interlocking applications, making it easy to pair with another contactor of the same model to form a forward and reverse motor circuit.
S0 frame 12A/5.5kW main circuit
AC-3 rated at 12A, 5.5kW (400V), insulation voltage 690V, mechanical life up to 10 million cycles.
