Wago 2002-3217 3-Level Terminal Block 2.5mm2 Grey

The Wago 2002-3217 is a professional-grade 3-level terminal block engineered for high-density electrical wiring applications. Designed to accommodate a 2.5mm2 cross-section, this component is specifically built to optimize space within control cabinets and distribution boards. By integrating three levels into a single compact housing, it allows for the efficient termination of L, N, and PE circuits, providing a robust and organized solution for complex electrical installations in both industrial and commercial environments.

Advantages

This terminal block offers significant space-saving benefits by stacking three connection levels vertically, which drastically reduces the footprint required on a DIN rail. The use of advanced spring pressure connection technology ensures that wires remain securely fastened even under conditions of vibration or thermal expansion, eliminating the need for periodic maintenance or retightening. Its modular design promotes a clean and systematic wiring layout, which simplifies troubleshooting and future system modifications while maintaining high electrical integrity.

Suitable for

• Control cabinet wiring
• Distribution board installations
• Industrial automation systems
• Commercial building electrical infrastructure
• Multi-circuit signal and power distribution

When it may not be suitable

This terminal block is not intended for use with conductors exceeding the specified 2.5mm2 cross-section capacity. It is also not suitable for high-current applications that require larger gauge wiring or environments where specialized explosion-proof or high-IP-rated enclosures are mandatory without additional protection.

Key specifications

• Connection type: Push-in CAGE CLAMP
• Cross-section: 2.5mm2
• Number of levels: 3
• Color: Grey
• Mounting: DIN-35 rail

How to use

To install the terminal block, snap it securely onto a standard DIN-35 rail. Insert the stripped conductor directly into the clamping unit until it reaches the stop. The spring-loaded mechanism automatically creates a reliable, gas-tight connection. To remove or adjust a wire, use a standard operating tool to release the spring pressure, allowing the conductor to be withdrawn easily without damaging the terminal or the wire.

What to consider before purchase

• Ensure the DIN rail type matches the mounting requirements.
• Verify that the conductor size is compatible with the 2.5mm2 rating.
• Check the total current and voltage requirements of your circuit.
• Confirm if additional accessories like end plates or jumpers are needed for your specific configuration.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring operations. Use appropriate wire strippers to maintain the correct strip length for optimal contact.
