Simet 4-pole screw terminal block ZZ 4-16.0, 76A, 800V

The Simet 4-pole screw terminal block ZZ 4-16.0 is a robust electrical component engineered for secure and reliable wire termination in demanding environments. Designed to handle high electrical loads, this terminal strip supports currents up to 76A and voltages up to 800V, making it an essential part of professional power distribution systems. Its construction ensures a firm mechanical connection, which is critical for maintaining stable conductivity and preventing overheating in both industrial and residential electrical setups.

Advantages

This terminal block offers exceptional durability and ease of installation, allowing for quick and secure connections of conductors ranging from 4 to 16 mm². The high-quality screw mechanism ensures that wires remain firmly in place, reducing the risk of loose connections over time. Its 4-pole configuration provides versatility for multi-circuit management, while the robust housing material offers excellent insulation properties, contributing to the overall safety and longevity of the electrical installation.

Suitable for

• Industrial power distribution panels
• Residential electrical wiring systems
• Connection of high-current electrical equipment
• Junction boxes requiring secure multi-conductor termination

This terminal block may not be suitable for applications involving extremely high-vibration environments where spring-loaded connectors might be preferred, or for use in specialized hazardous areas requiring explosion-proof certification. It is also not intended for direct exposure to moisture or corrosive elements without an appropriate protective enclosure.

Key specifications

• Number of poles: 4
• Rated current: 76A
• Rated voltage: 800V
• Conductor cross-section range: 4 to 16 mm²
• Connection type: Screw terminal

To use the terminal block, first ensure that the power supply is completely disconnected. Strip the insulation from the ends of your conductors to the appropriate length, insert the wires into the terminal ports, and tighten the screws firmly to ensure a solid mechanical and electrical contact. Verify that no loose strands are protruding and that the wires are securely held before restoring power to the circuit.

What to consider before purchase

• Verify that the conductor size falls within the 4-16 mm² range
• Ensure the current and voltage ratings meet your specific circuit requirements
• Check that the physical dimensions fit within your intended enclosure or panel

For optimal performance and safety, always ensure that the screws are tightened to the manufacturer's recommended torque and periodically inspect the connections for any signs of thermal stress or loosening, especially in high-load applications.
