## Long description

The Siemens 5ST3738 is a professional-grade 3-phase pin-type busbar engineered for streamlined power distribution within electrical panels and distribution boards. Designed to accommodate modular devices, this component features a 10 mm2 cross-section and supports up to 12 modules, ensuring a stable and secure electrical connection. Its robust construction and touch-safe design contribute to enhanced safety standards in complex electrical installations.
Advantages
This busbar significantly reduces wiring time and complexity by providing a unified power supply path for multiple modular devices. The pin-type design ensures a reliable mechanical and electrical contact, while the touch-safe construction minimizes the risk of accidental contact during maintenance. Being cuttable to size, it offers high flexibility for various installation layouts, and the included end caps ensure that the open ends are properly insulated to maintain safety standards.
Suitable for
Power distribution in residential and commercial electrical distribution boards
Connecting multiple miniature circuit breakers or residual current devices
Professional electrical installations requiring high reliability
When it may not be suitable
This busbar is not intended for use in high-current industrial applications exceeding its 10 mm2 capacity. It is also not compatible with devices that require fork-type connections or those that do not adhere to standard modular spacing.
Key specifications
Phase configuration: 3-phase
Cross-section: 10 mm2
Connection type: Pin-type
Capacity: 12 modules
Length: 214 mm
Features: Touch-safe, cuttable, includes end caps
How to use
To install the busbar, first measure the required length based on the number of modular devices in your distribution board. If necessary, cut the busbar to the desired length using appropriate tools and ensure that the cut edges are clean. Attach the provided end caps to the exposed ends to maintain the touch-safe rating. Insert the pins into the terminals of the modular devices and tighten the terminal screws securely to ensure a firm electrical connection.
What to consider before purchase
Verify that the total current load does not exceed the rating for a 10 mm2 cross-section
Ensure your modular devices are compatible with pin-type busbar connections
Check the physical space available in your distribution board for the 214 mm length
Usage recommendations: Always ensure that the main power supply is disconnected before performing any installation or maintenance work on electrical distribution boards. Use only calibrated tools for tightening terminal screws to prevent damage to the busbar or the modular devices.
