Product Positioning

The SIRIUS 3RT2024-2BB40 is an S0 frame contactor, rated at 12A AC-3, with an output of 5.5kW at 400V. The coil voltage is 24V DC, and the terminals use a spring clip for quick fixation. It comes standard with 1NO+1NC instantaneous auxiliary contacts, and the entire unit weighs approximately 0.612 kg. Like the 2FB40, it uses a 24V DC coil, but its auxiliary contacts are standard type and it lacks reversible interlocking for forward and reverse rotation, making it suitable for general motor control circuits with unidirectional operation. Kenxin Motors provides stock and technical consultation.

Core Product Advantages and Features
24V DC coil with spring terminals
Combining the signal stability of DC coils with the quick wiring advantages of spring terminals, it is suitable for large-scale automated panel assembly.
1NO+1NC standard auxiliary contact
It provides basic status feedback function and shares the same auxiliary contact specifications with products in the same series such as 2AP00 and 2AL20.
S0 frame 12A/5.5kW main circuit
The AC-3 is rated at 12A and 5.5kW (400V), and shares the same main contactor frame and current rating as the entire 3RT2024 series.
Net weight approximately 0.612 kg
The entire unit, including the spring terminal block, weighs 0.612kg, which is slightly heavier than the screw terminal version, but offers higher wiring efficiency.
