## Long description

The Siemens 5ST3702 is a professional-grade single-phase comb busbar engineered for streamlined electrical distribution within modular installations. With a robust 16 mm² cross-section and a precise length of 214 mm, this component provides a reliable and efficient method for interconnecting circuit breakers and various DIN-rail mounted devices. Its design facilitates organized panel wiring, reducing the need for individual jumper wires and ensuring a clean, safe electrical connection in industrial and residential distribution boards.
Advantages
This busbar offers significant benefits for electrical system assembly, primarily by simplifying the wiring process and minimizing potential points of failure. The high-quality construction ensures excellent conductivity and long-term durability, which is essential for maintaining stable power distribution. By utilizing a standardized comb design, it allows for rapid installation and consistent spacing, which helps in maintaining a professional and orderly layout within the electrical enclosure.
Suitable for
Electrical distribution boards and consumer units
Connecting multiple miniature circuit breakers
Modular DIN-rail mounted electrical systems
Professional electrical panel wiring
When it may not be suitable
This busbar is designed specifically for single-phase applications and cannot be used for three-phase distribution systems. Furthermore, it is not suitable for installations requiring a cross-section larger than 16 mm² or for configurations where the physical length of 214 mm does not align with the specific spacing of the installed modular components.
Key specifications
Phase type: Single-phase
Cross-section: 16 mm²
Length: 214 mm
Colour: Grey
Mounting type: DIN-rail component compatible
How to use
To install the Siemens 5ST3702, ensure that the power supply to the distribution board is completely disconnected. Cut the busbar to the required length if necessary, ensuring that the exposed copper ends are properly insulated or capped according to safety standards. Insert the comb teeth into the terminal slots of the circuit breakers or modular devices mounted on the DIN-rail. Once positioned, tighten the terminal screws securely to ensure a firm electrical contact and prevent overheating due to loose connections.
What to consider before purchase
Verify that your circuit breakers are compatible with comb-type busbar connections.
Ensure the 16 mm² cross-section meets the current-carrying requirements of your specific circuit.
Check the physical dimensions to ensure the 214 mm length is sufficient for the number of modules being connected.
Confirm that the installation is strictly for a single-phase electrical system.
Usage recommendations: Always perform a final inspection of all terminal connections after installation to ensure they are tightened to the manufacturer's specified torque. Use appropriate end caps to cover exposed live parts to maintain safety standards.
