## Long description

The ONKA Elektrik OPK universal spring terminal block is a high-quality component engineered for secure and efficient wire termination in electrical installations. Designed for conductors with a cross-section of 2.5mm2, this grey terminal block utilizes a robust spring-clamp mechanism that ensures consistent contact pressure and long-term reliability. Its compact design allows for space-saving installation in control panels and distribution boards, providing a professional solution for managing complex wiring systems.
Advantages
The primary benefit of this terminal block is its advanced spring-clamp technology, which eliminates the need for manual screw tightening and provides excellent resistance to vibrations. This feature significantly reduces installation time and maintenance requirements, as the connection remains stable even in demanding industrial environments. The high-quality materials used in its construction ensure durability and optimal electrical conductivity, contributing to the overall safety and performance of the electrical system.
Suitable for
Industrial control panels
Commercial electrical distribution systems
Automation and instrumentation wiring
Building management systems
This terminal block may not be suitable for applications involving conductors larger than 2.5mm2 or for environments requiring specialized high-current power distribution beyond its rated capacity. It is also not intended for direct outdoor exposure without a suitable protective enclosure.
Key specifications
Conductor capacity: 2.5mm2
Connection type: Spring-clamp
Color: Grey
Material: Flame-retardant thermoplastic
Mounting: DIN rail compatible
To use the terminal block, strip the insulation from the wire to the recommended length and insert the conductor into the spring-clamp opening. The mechanism automatically secures the wire, creating a reliable electrical connection without the need for specialized tools. To remove the wire, use a standard screwdriver to depress the release lever, allowing the conductor to be extracted safely.
What to consider before purchase
Ensure the wire gauge matches the 2.5mm2 capacity
Verify the total number of connections required for your project
Check compatibility with existing DIN rail mounting systems
For optimal performance, ensure that all wires are stripped to the correct length and fully inserted into the terminal block. Regularly inspect connections in high-vibration environments to maintain system integrity.
