## Long description

The Wago 870-503 is a professional double-deck terminal block engineered for high-density electrical wiring applications. With a compact design and a conductor capacity of 2.5 mm², this component allows for efficient space utilization within industrial control cabinets and complex distribution systems. The grey housing provides a clear visual distinction for organized wiring layouts, while the robust construction ensures long-term reliability and secure electrical contact in demanding environments.
Advantages
The primary benefit of this double-deck terminal block is its ability to double the wiring density compared to standard single-level blocks, making it an essential component for projects where panel space is limited. Its high-quality materials and precise engineering facilitate quick and secure connections, reducing installation time and maintenance requirements. The 500 V rating provides sufficient headroom for a wide range of standard industrial control and automation tasks, ensuring consistent performance under load.
Suitable for
Industrial control cabinet wiring
Electrical distribution systems
Automation and control panels
High-density terminal rail assemblies
When it may not be suitable
This terminal block is not intended for use with conductors exceeding 2.5 mm² in cross-section, as attempting to connect larger wires may damage the terminal or result in an insecure connection. It is also not designed for high-power distribution applications that exceed its rated voltage or current capacity.
Key specifications
Conductor capacity: 2.5 mm²
Rated voltage: 500 V
Width: 5 mm
Depth: 70 mm
Height: 40 mm
Color: Grey
How to use
To install the Wago 870-503, mount the terminal block onto a standard DIN rail by snapping it into place until it is firmly secured. Strip the insulation from your conductors to the recommended length and insert them into the appropriate terminal points. Ensure that the wires are fully seated to maintain a reliable electrical connection. For multi-level wiring, utilize the upper and lower decks to separate different circuit paths while maintaining a compact footprint.
What to consider before purchase
Verify that the 2.5 mm² conductor size is compatible with your specific wiring requirements.
Ensure that the 500 V rating meets the electrical specifications of your circuit.
Check the available space on your DIN rail to accommodate the 5 mm width of the block.
Usage recommendations
Always ensure that power is disconnected from the circuit before performing any installation or maintenance work on terminal blocks to prevent electrical hazards.
