Wago 279-501 2-Level Terminal Block, 1.5mm2, Grey

The Wago 279-501 is a professional 2-level terminal block designed for secure and efficient electrical connections. This double-deck terminal block serves as a reliable through terminal block, specifically engineered to optimize space in industrial control cabinets and distribution boards. By utilizing a dual-level design, it allows for high-density wiring while maintaining clear organization of electrical circuits.

Advantages

The primary advantage of this terminal block is the integration of the CAGE CLAMP connection technology, which ensures maintenance-free and vibration-resistant contact. This system allows for the connection of various conductor types without the need for specialized preparation, such as crimping ferrules, which significantly reduces installation time. The compact design helps save valuable space in enclosures, and the robust construction ensures long-term durability in demanding electrical environments.

Suitable for

• Industrial control cabinets
• Electrical distribution boards
• High-density wiring applications
• General electrical installation projects

When it may not be suitable

This terminal block is designed for conductors with a cross-section up to 1.5 mm². It is not suitable for applications requiring larger wire gauges or high-power connections that exceed its rated capacity. Additionally, it is intended for standard indoor environments and may require additional protection if used in extreme conditions.

Key specifications

• Conductor capacity: 0.08 mm² to 1.5 mm²
• Connection technology: CAGE CLAMP
• Width: 4 mm
• Height: 85 mm
• Depth: 43.8 mm
• Configuration: 2-level through terminal block
• Quantity: 50 pieces per pack

How to use

To use the Wago 279-501, first ensure the conductor is stripped to a length of 8 to 9 mm. Using the CAGE CLAMP mechanism, insert the conductor directly into the terminal point. The spring-loaded clamp automatically secures the wire, providing a reliable connection without the need for additional tools or ferrules. Repeat this process for each level as required by your circuit layout.

What to consider before purchase

• Verify that your conductor cross-section falls within the 0.08 mm² to 1.5 mm² range.
• Ensure the 4 mm width is compatible with your existing DIN rail layout.
• Confirm the total number of connection points needed for your project to match the 50-piece pack quantity.

Usage recommendations

For optimal performance and safety, always ensure that the conductors are stripped to the correct length of 8 to 9 mm. Avoid using damaged wires and ensure that the terminal block is securely mounted on a compatible DIN rail before making connections.
