Rated for 250A and 690V, it features multiple connection points including 1x35-120mm2, 2x2,5-25mm2, 5x2,5-16mm2, and 4x2,5-10mm2 terminals. This DIN-rail mountable block provides a reliable solution for organizing cable connections in industrial and commercial electrical panels, ensuring secure and orderly power management.

## Long description

The Siemens 5ST2508 is a high-performance 1-pole distribution block engineered for efficient and organized electrical power management in industrial and commercial environments. Designed as part of the SENTRON series, this component serves as a reliable interface for branching power circuits, ensuring that cable connections remain secure and orderly within electrical panels. Its robust construction and standardized design make it an essential element for maintaining professional electrical installations.
Advantages
This distribution block offers significant benefits for electrical system design, primarily through its versatile terminal configuration which allows for the connection of various cable cross-sections in a single compact unit. The device is built for ease of installation, featuring universal mounting capabilities on standard DIN rails. Furthermore, the integrated touch protection provides an essential safety layer, minimizing the risk of accidental contact during maintenance or operation, while the high current rating ensures consistent performance under demanding electrical loads.
Suitable for
Industrial control panels
Commercial power distribution systems
Electrical cabinets requiring organized cable management
Integration with miniature circuit breakers and residual current devices
When it may not be suitable
This distribution block is designed for specific electrical distribution tasks and may not be suitable for applications requiring multi-pole phase distribution, as it is a 1-pole device. Additionally, it should not be used in environments that exceed its rated voltage or current specifications, nor in applications where specialized environmental protection beyond standard panel mounting is required.
Key specifications
Number of poles: 1
Rated current: 250 A (IEC) / 230 A (UL)
Rated voltage: 1000 V AC / 1500 V DC (IEC) / 600 V AC/DC (UL)
Input terminal: 1x 35-120 mm2
Output terminals: 2x 2.5-35 mm2, 5x 2.5-16 mm2, 4x 2.5-10 mm2
Mounting type: DIN-rail
How to use
The Siemens 5ST2508 is designed for quick and convenient installation. Begin by securing the block onto a standard DIN rail within your electrical enclosure. Once mounted, insert the main power cable into the primary input terminal and tighten the connection to the manufacturer's specified torque. Subsequently, connect the secondary distribution cables into the appropriate output terminals based on their cross-sectional area. Ensure all connections are firm and that the touch protection covers are properly seated before energizing the system.
What to consider before purchase
Verify that the current and voltage requirements of your circuit do not exceed the device ratings.
Ensure the cable cross-sections you intend to use are compatible with the specified terminal ranges.
Confirm that you have sufficient space on the DIN rail within your electrical panel.
Check that a 1-pole configuration meets the specific requirements of your electrical distribution layout.
Usage recommendations
Always ensure that the power supply is completely disconnected before performing any installation or maintenance work on the distribution block. Use appropriate tools for tightening terminals to prevent loose connections, which can lead to overheating. Regularly inspect the connections during routine maintenance to ensure long-term reliability and safety.
