ELEKTROPLAST WLZ35/3x50/n Three-Pole Branching Block for AL/CU 3x50mm2, Blue, DIN Rail and Surface Mount

The ELEKTROPLAST WLZ35/3x50/n is a professional three-pole branching block engineered for the secure and efficient distribution of electrical power. Designed to accommodate both aluminum and copper conductors with cross-sections up to 50mm2, this terminal block provides a robust solution for complex wiring requirements in electrical cabinets. Its durable blue housing ensures clear identification within power distribution systems, while the flexible mounting options allow for installation on standard TH35 DIN rails or directly onto flat surfaces using screws.

Advantages

This branching block offers exceptional versatility by supporting both rigid and flexible conductors, making it highly adaptable for various electrical infrastructure projects. The high-quality construction ensures low contact resistance and long-term reliability, which is critical for maintaining stable power distribution. Its compact design helps optimize space within crowded electrical panels, while the dual-mounting capability simplifies the installation process for technicians, reducing labor time and improving overall organization of cable management.

Suitable for

• Industrial power distribution boards
• Residential electrical panels
• Commercial building wiring systems
• Main power supply branching
• Connection of aluminum and copper cables

When it may not be suitable

This branching block is not intended for use with conductors exceeding 50mm2 in cross-section, as this may compromise the integrity of the connection. It is also not suitable for high-vibration environments unless additional strain relief measures are implemented for the connected cables.

Key specifications

• Number of poles: 3
• Maximum conductor cross-section: 50mm2
• Compatible conductor materials: Aluminum and Copper
• Mounting options: TH35 DIN rail or flat surface
• Color: Blue

How to use

To install the block, first ensure that the power supply is disconnected. If mounting on a TH35 DIN rail, snap the unit securely onto the rail until it clicks into place. For surface mounting, use the integrated mounting holes to fix the block firmly to the desired panel surface. Strip the insulation from your aluminum or copper conductors according to the required length, insert them into the terminal ports, and tighten the screws to the specified torque to ensure a secure electrical connection. Verify that all cables are firmly held before restoring power.

What to consider before purchase

• Verify the total current load of your system to ensure it matches the block's capacity.
• Check the available space in your electrical enclosure for mounting.
• Ensure the conductor cross-section is within the supported 50mm2 range.
• Confirm compatibility with your existing DIN rail system or surface mounting requirements.

Usage recommendations

Always use appropriate tools for tightening terminal screws to prevent damage to the conductors or the block housing. Ensure that aluminum conductors are treated with suitable contact grease if required by local electrical regulations to prevent oxidation.
