Product Positioning
The Siemens SIRIUS 3RH2122-1VB40 is an S00 frame coupled auxiliary contactor with a 24V DC coil and built-in diode. It has a permissible voltage range of 0.85 to 1.85 times the rated value, uses a screw terminal design, and provides 4 sets of contacts: 2NO and 2NC.
Core Product Advantages and Features
Built-in diode coil protection
The coil has a built-in diode, which can suppress the surge generated at the moment of power failure and protect the control circuit components.
Tolerance voltage range
The voltage tolerance range is 0.85 to 1.85 times the rated value, and it has a high adaptability to power fluctuations.
2NO+2NC quadrupole contacts
Two sets of normally open and two sets of normally closed contacts are provided in parallel, which is suitable for forming signal interlocking and feedback circuits.
Screw terminal secure wiring
The traditional screw terminal design ensures secure and reliable wiring, making it suitable for control panels that require regular maintenance and repair.
