Wago 264-737 4-Conductor PE Terminal Block

The Wago 264-737 is a high-quality 4-conductor protective earth (PE) terminal block engineered for secure and reliable grounding in electrical installations. Designed for seamless integration into industrial and commercial wiring systems, this component provides a robust connection point for grounding conductors. Its compact form factor allows for efficient use of space within control cabinets and distribution boards, while the 4-conductor design facilitates organized wiring management.

Advantages

This terminal block offers exceptional mechanical stability and electrical reliability, ensuring that grounding connections remain secure even under vibration or thermal stress. The design simplifies the installation process by allowing multiple conductors to be connected to a single grounding point, which reduces the need for additional bridging components. Its durable construction and standardized mounting interface ensure long-term performance and compatibility with common DIN rail systems, making it a dependable choice for professional electrical engineering projects.

Suitable for

• Industrial control panels and automation systems
• Commercial building electrical distribution
• Grounding applications requiring multiple conductor connections
• DIN rail mounted electrical enclosures

When it may not be suitable

This terminal block is specifically designed for protective earth (PE) grounding applications and should not be used for phase or neutral power distribution. It is not intended for conductors exceeding 2.5 mm² in cross-section, and attempting to use larger gauge wires may result in improper contact or mechanical failure.

Key specifications

• Conductor capacity: 2.5 mm²
• Number of connection points: 4
• Mounting type: DIN rail
• Width: 10 mm
• Depth: 46.5 mm
• Height: 24.5 mm
• Color: Yellow-green (standard PE identification)

How to use

To install the Wago 264-737, snap the terminal block onto a compatible DIN rail until it is firmly seated. Strip the insulation from your conductors according to the manufacturer's recommended length. Insert the conductors into the connection points, ensuring they are fully seated to establish a reliable electrical contact. The terminal block automatically creates a conductive path to the DIN rail, providing the necessary grounding function for the connected circuits.

What to consider before purchase

• Verify that your DIN rail type is compatible with the mounting mechanism
• Ensure the conductor cross-section is exactly 2.5 mm² for optimal fit
• Confirm that the total number of conductors per circuit does not exceed the capacity of the block

Usage recommendations

Always ensure that the DIN rail itself is properly grounded to the main protective earth bus of the installation to maintain the integrity of the grounding system.
