ONKA Elektrik Universal Screw Terminal Block 1.5mm2 Blue

The ONKA Elektrik universal screw terminal block is a professional-grade electrical component engineered for secure and reliable wire terminations. Designed to accommodate conductors with a cross-section of 1.5mm2, this terminal block features a robust screw-clamp mechanism that ensures high-integrity electrical contact and long-term stability. Its blue housing allows for easy identification in complex wiring systems, making it an essential part of modern electrical distribution and control panel assemblies.

Advantages

This terminal block offers exceptional mechanical strength and vibration resistance, ensuring that connections remain secure even in demanding environments. The high-quality materials used in its construction provide excellent electrical conductivity and thermal stability, minimizing energy loss and preventing overheating. Its compact design facilitates efficient space utilization within enclosures, while the intuitive screw-terminal interface allows for quick and straightforward installation without the need for specialized crimping tools.

Suitable for

• Electrical distribution boards
• Industrial control panels
• Automation and instrumentation systems
• Building electrical installations

This terminal block may not be suitable for applications requiring high-current power distribution exceeding its 1.5mm2 capacity or for environments exposed to extreme corrosive chemicals that could degrade the plastic housing. It is also not intended for direct underwater use or applications requiring specific IP-rated waterproof enclosures.

Key specifications

• Conductor capacity: 1.5mm2
• Connection type: Screw terminal
• Color: Blue
• Application: Professional electrical wiring

To use the terminal block, strip the insulation from the end of the wire to the recommended length, insert the conductor into the terminal opening, and tighten the screw firmly to secure the connection. Ensure that the wire is fully seated and that no loose strands are protruding from the terminal before applying power to the circuit.

What to consider before purchase

• Verify that the wire gauge matches the 1.5mm2 capacity
• Check the available space in your mounting rail or enclosure
• Ensure compatibility with your existing terminal block system

For optimal performance and safety, always ensure that all screw connections are tightened to the manufacturer's specified torque and perform regular inspections of the wiring to maintain system integrity.
