Series Overview
Series Overview
- SIRIUS 3SB3 is a control device for front - panel mounting and rear - panel wiring, available in both metal and plastic series.
- The appearance design of SIRIUS is flat and streamlined, making the entire control panel very coordinated and beautiful. The snap - in mounting structure is ingeniously designed, greatly improving the installation efficiency. In addition, the SIRIUS metal series has a very high protection level, reaching IP67 and NEMA4.
Standards
- IEC60947, EN60947 - 1 (DIN VDE 0660 Part 100), IEC60947 - 5 - 1, EN60947 - 5 - 1 (DIN VDE 0660 Part 200)
Design
- The plastic series has a flat shape, including round and square. The metal series only has a round shape.
- The flat shape makes the plastic series and the thin - film button combination very coordinated and easy to clean.
- The operating surfaces of buttons and illuminated buttons are concave. The lenses of indicators are convex.
Inscriptions
- Inscriptions can be directly laser - engraved on the surface of components or engraved on nameplates or backplanes, and a labeling system can also be used.
Structure
- A control device consists of three parts: the button head or light cover on the front of the panel, the mounting base behind the panel, and the contact block or lamp socket.
- The mounting base of the round series can be used on both sides. One side is suitable for panels with a thickness of 1 - 4mm, and the other side is suitable for panels with a thickness of 3 - 6mm.
- The mounting base of the square series is only suitable for panels with a thickness of 1 - 4mm.
- A button with a regular configuration can be installed with two contact blocks. When three contact blocks or one lamp socket + two contact blocks are needed, a 3 - position bracket (3SB3901 - 0AB) must be inserted at the rear of the button head. For knob switches, key switches, and double - button units, a 3 - position bracket (3SB3901 - 0AC) with a central contact drive piece needs to be inserted.
- For the convenience of users in selection, we have established order numbers for sets of devices for some commonly used models, which can meet the needs of most applications.
Base
- When delivered, the mounting position of the base is suitable for panels with a thickness of 1 - 4mm, that is: the arrow of ▲1 - 4mm▲ faces forward, and the tightening screw is at the lower right corner. When the panel thickness is 3 - 6mm, the base needs to be reversed, that is: the arrow of ▲3 - 6mm▲ faces forward, and the tightening screw is at the upper right corner. In this case, the tightening screw must be turned counterclockwise to the end before the base is installed.
Contact Blocks and Lamp Sockets
- There is a slow - action contact with a double - break contact bridge structure (1NC or 1NO) inside the contact block. This structure ensures that the 3SB3 button switch has very high reliability even under low voltage and low current (such as 5V/1mA1). They are suitable for electronic systems and conventional electrical control.
- The normally closed (NC) contact realizes the safety function through forced disconnection.
- BA9s (screw connection) and W2×4.6d (solder connection) lamp sockets can be used for illuminated buttons and signal lamps.
- Both the contact block and the lamp socket have terminal markings conforming to EN50013.
Installation
- SIRIUS devices can be installed simply and quickly:
- Insert the button head or light head from the front of the control panel
- Install the base from the rear
- Tighten the screws on the base
- Snap the contact block or lamp socket directly onto the base
Wiring Methods
- Screw - connected terminals
- Cage - clamp terminals
- Solder connection (0.8×0.8mm)
- The screw - connected terminals of 3SB3 have SIGUT wiring technology. The anti - vibration structure prevents the screws from detaching from the main body during transportation. When delivered, the screws are in a loose state. Open terminals, trumpet - shaped wiring holes, and guide holes greatly improve installation efficiency. Electric screwdrivers can be used.
- Cage - clamp spring - connected terminals: Fast installation and can be closely arranged.
Button Boxes
- For round buttons, plastic button boxes can be equipped with 1, 2, 3, 4, 6 control points. Control points above 6 (round or square buttons) can also be supplied as required.
Communicable SIRIUS 3SB3
- The 4I/4O AS - i user module with a chip can connect SIRIUS control components to the AS - i network system.
Connection Methods
- AS - i user module for circuit boards
- Single - piece connection method
- AS - i front panel module
- AS - i button box
- SIRIUS can also communicate with PROFIBUS - DP.
