ELEKTROPLAST WLZ35P/240/z Single-Pole Distribution Block for AL/CU Cables 35-240mm2, Yellow-Green, TH Rail and Surface Mount

The ELEKTROPLAST WLZ35P/240/z is a professional single-pole distribution block engineered for the secure connection and distribution of aluminum and copper conductors. Designed to accommodate cable cross-sections from 35mm2 to 240mm2, this component provides a robust solution for managing high-current power lines within electrical cabinets. Its distinctive yellow-green housing ensures easy identification for grounding or protective earth applications, while the versatile design allows for both direct surface mounting and installation on standard TH rails.

Advantages

This distribution block offers exceptional reliability for electrical installations by providing a stable contact point for large-gauge cables. The construction is optimized for both copper and aluminum wiring, preventing galvanic corrosion and ensuring long-term electrical conductivity. Its compact design saves valuable space in distribution boards, and the dual-mounting capability provides flexibility for various enclosure types, making it a highly adaptable choice for complex electrical infrastructure.

Suitable for

• Industrial power distribution panels
• Residential electrical main switchboards
• Grounding and protective earth systems
• Large-scale electrical infrastructure projects

When it may not be suitable

This distribution block is not intended for use with cables smaller than 35mm2, as the terminal mechanism is specifically calibrated for larger cross-sections. It is also not suitable for environments exposed to extreme moisture or corrosive chemical vapors unless housed within an appropriate IP-rated enclosure.

Key specifications

• Conductor range: 35mm2 to 240mm2
• Material compatibility: Aluminum and Copper
• Mounting options: TH rail and flat surface
• Color: Yellow-Green
• Pole configuration: Single-pole

How to use

To install the block, first ensure the power supply is completely disconnected. If mounting on a TH rail, snap the unit securely onto the rail until it clicks into place; for surface mounting, use the integrated screw holes to fix the block firmly to the backplane. Strip the insulation from your conductor to the required length, insert the cable into the terminal, and tighten the screw to the manufacturer-specified torque to ensure a secure connection. Verify that the cable is held firmly and cannot be pulled out before restoring power.

What to consider before purchase

• Verify that your cable cross-section falls within the 35-240mm2 range.
• Confirm the available space in your electrical panel for mounting.
• Ensure the mounting method (TH rail or surface) matches your enclosure design.

Usage recommendations

Always use a calibrated torque screwdriver to tighten the terminal screws, as this prevents damage to the conductor strands and ensures the connection remains stable under thermal expansion and contraction.
