Siemens 5ST3774-0 Pin Busbar 10mm2 1P+N 1000mm

The Siemens 5ST3774-0 pin busbar is a high-quality electrical component designed for efficient power distribution in 1P+N installations. With a cross-section of 10mm² and a total length of 1000mm, this busbar is specifically engineered to support compact modular devices, including the 5SV1, 5SV6, and 5SL60 series. It serves as a reliable solution for connecting multiple miniature circuit breakers and residual current devices within a distribution board, facilitating a clean and organized electrical layout.

Advantages

This busbar offers significant benefits for electrical panel assembly by providing a standardized and secure method for power distribution. Its design ensures touch protection, which enhances safety during both the installation process and regular operation. The busbar is highly versatile, as it can be cut to the required length to fit specific distribution board configurations, allowing for flexible planning and installation. By using this component, installers can reduce the amount of individual wiring required, which minimizes the risk of connection errors and improves the overall reliability of the electrical system.

Suitable for

• Power distribution in 1P+N electrical installations
• Connecting compact miniature circuit breakers and residual current devices
• Modular distribution boards requiring organized wiring
• Projects where space-saving compact devices are utilized

When it may not be suitable

This busbar is specifically designed for 1P+N compact devices and may not be compatible with standard-width modular components or different phase configurations. It is not suitable for high-current applications exceeding the 10mm² capacity or for installations requiring different connection terminal types.

Key specifications

• Cross-section: 10mm²
• Configuration: 1P+N (1-pole + Neutral)
• Length: 1000mm
• Design: Pin-type
• Compatibility: Compact devices (5SV1, 5SV6, 5SL60 series)
• Safety: Touch-protected

How to use

To use the busbar, first determine the required length for your specific distribution board layout and cut the busbar accordingly using appropriate tools. Ensure that the power supply is disconnected before beginning any installation work. Insert the pins into the corresponding terminals of the modular devices, ensuring a firm and secure fit. Once positioned, tighten the terminal screws to establish a reliable electrical contact. Always verify that the touch protection is intact and that all connections are properly seated before restoring power to the system.

What to consider before purchase

• Verify the compatibility of your circuit breakers with the pin-type connection
• Ensure the 10mm² cross-section meets the current requirements of your circuit
• Check the total number of modules to ensure the 1000mm length is sufficient
• Confirm that your installation requires a 1P+N configuration

Usage recommendations

Always ensure that the busbar is cut cleanly and that no metal shavings remain in the distribution board. Use end caps if necessary to maintain the touch-protection rating after cutting the busbar to size.
