ONKA Elektrik MRK-C 2-Level Screw Terminal Block 2.5mm2 Grey

The ONKA Elektrik MRK-C 2-level screw terminal block is a high-quality electrical component engineered for reliable wire termination in demanding industrial environments. Designed to accommodate conductors up to 2.5mm2, this grey terminal block provides a compact solution for complex wiring systems where space optimization is critical. Its robust construction ensures excellent mechanical stability and consistent electrical conductivity, making it a dependable choice for professional electrical installations.

Advantages

The primary benefit of the MRK-C series is its dual-level design, which effectively doubles the wiring density within a control panel compared to single-level blocks. This space-saving configuration allows for cleaner, more organized wiring layouts, reducing the overall footprint of distribution boards. The screw connection technology provides a secure, vibration-resistant contact that maintains integrity over long periods of operation, ensuring minimal maintenance requirements and high safety standards for various electrical circuits.

Suitable for

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

This terminal block may not be suitable for high-current power distribution applications exceeding its 2.5mm2 capacity or for environments requiring specialized explosion-proof or high-IP rated enclosures without additional protection. It is intended for standard DIN rail mounting and may not fit in non-standard or custom-built small-scale electronic housings.

Key specifications

• Connection type: Screw terminal
• Levels: 2-level
• Capacity: 2.5mm2
• Color: Grey
• Mounting: DIN rail

To use the terminal block, mount it securely onto a standard DIN rail within your enclosure. Strip the insulation from your electrical wires to the appropriate length, insert the conductor into the designated terminal opening, and tighten the screw firmly to ensure a solid mechanical and electrical connection. Ensure that the wire size matches the terminal capacity to prevent overheating or loose connections.

What to consider before purchase

• Verify the total number of connections required for your project
• Ensure the DIN rail type in your enclosure is compatible
• Check that your wire gauge does not exceed the 2.5mm2 limit

Usage recommendations: Always ensure that all screw connections are tightened to the manufacturer's recommended torque specifications to prevent loose contacts. Periodically inspect the terminal blocks for signs of wear or thermal stress in high-vibration environments.
