The Siemens 3RF3405-1BB04 is a robust solid state contactor designed for seamless integration into various industrial applications. This three-pole device features two normally open (NO) contacts and is engineered to handle operating voltages ranging from 48 to 480 V at both 50 and 60 Hz, making it versatile for global use. With an operational current of 5.2 A at AC-3 at 400 V and a rated operating power of 2.2 kW, it is suitable for managing moderate power loads in a compact form factor.
The contactor is two-phase controlled and offers instantaneous switching, ensuring minimal delay in operations. It is designed for vertical mounting and can be easily installed onto a standard 35 mm mounting rail, with provisions for side-by-side mounting to optimise space within control cabinets. The unit's dimensions are 95 mm in height, 45 mm in width, and 100.8 mm in depth, requiring minimal space while providing maximum functionality.
For the control circuit, the contactor utilises a DC control supply voltage with a rated value of 24 V. It has a symmetrical line frequency tolerance of 5 Hz and an operating range factor for the control supply voltage rated value at DC between 0.63 and 1.25. The control current at the DC rated value is 15 mA, ensuring reliable operation.
The contactor is equipped with screw-type terminals for both the main current circuit and auxiliary and control circuit, accommodating a range of conductor cross-sections for flexible installation options. The device is designed with a focus on durability and reliability, featuring a surge current resistance rated value of 200 A and an I2t value maximum of 200 A²·s.
This solid state contactor is an excellent choice for those seeking a dependable solution for controlling power circuits in industrial environments, offering both performance and ease of use.
