## Long description

The Wago 280-941/281-492 is a professional-grade 4-pole double-deck diode terminal block designed for efficient DIN-rail mounting. This component is engineered to provide reliable signal routing and circuit protection within industrial control panels and automation systems. With its compact double-deck architecture, it allows for high-density wiring, making it an essential solution for complex electrical installations where space optimization is critical.
Advantages
The primary advantage of this terminal block is its space-saving design, which effectively doubles the connection density compared to standard single-level blocks. The integrated diode functionality provides essential circuit protection, preventing reverse current flow and ensuring the integrity of sensitive control signals. Its robust construction ensures long-term reliability in demanding industrial environments, while the standardized DIN-rail mounting facilitates quick and easy installation or replacement during maintenance.
Suitable for
Industrial automation control panels
Signal routing in complex electrical circuits
Protection of sensitive electronic components from reverse polarity
High-density wiring applications in switchgear
When it may not be suitable
This terminal block is not intended for high-power applications requiring large conductor cross-sections beyond 2.5mm². It is also not suitable for environments where extreme moisture or corrosive substances are present without additional protective enclosures.
Key specifications
Connection capacity: 2.5mm²
Number of poles: 4
Mounting type: DIN-rail
Width: 5 mm
Depth: 64 mm
Height: 58.5 mm
Color: Grey
How to use
To install the terminal block, snap it onto a standard DIN-rail until it clicks securely into place. Insert the stripped conductors into the terminal points according to your wiring diagram. Ensure that the wires are fully seated to maintain a secure electrical connection. The double-deck design allows for independent wiring on each level, simplifying the organization of complex control circuits.
What to consider before purchase
Verify that the 2.5mm² wire capacity meets your specific circuit requirements.
Ensure the DIN-rail type in your enclosure is compatible with standard mounting dimensions.
Check the diode specifications to ensure they align with your circuit's voltage and current needs.
Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Use appropriate wire strippers to avoid damaging the conductors, and verify all connections for tightness to prevent overheating or signal loss.
