## Summary description

The ONKA Elektrik MRK screw terminal block is a high-quality electrical component designed for secure wire connections in industrial and commercial control panels. With a 16mm2 capacity, this gray terminal block ensures reliable conductivity and mechanical stability on DIN rails. It is an essential solution for professional electrical installations, providing efficient organization and safe distribution of power within electrical cabinets.

## Long description

The ONKA Elektrik MRK screw terminal block is a professional-grade electrical component engineered for secure and reliable wire termination in industrial and commercial control panels. Designed to accommodate conductors up to 16mm2, this terminal block provides excellent mechanical stability and electrical conductivity when mounted on standard DIN rails. Its robust construction ensures long-term performance in demanding environments, making it a fundamental building block for organized and safe power distribution systems within electrical cabinets.
Advantages
This terminal block offers superior connection integrity through its high-quality screw clamping mechanism, which maintains constant pressure on the conductor to prevent loosening due to vibrations or thermal expansion. The compact gray housing is manufactured from durable, flame-retardant materials that meet rigorous safety standards for electrical installations. Its design facilitates efficient space utilization on the mounting rail, allowing for clean and systematic wiring layouts that simplify maintenance and troubleshooting tasks.
Suitable for
Industrial control panels and automation systems
Commercial electrical distribution cabinets
Power supply and signal distribution circuits
General electrical infrastructure projects
When it may not be suitable
This terminal block is not intended for use in environments with extreme corrosive gases or high-moisture conditions unless housed in an appropriately rated enclosure. It is also not suitable for applications requiring tool-less push-in connections or for conductors exceeding the specified 16mm2 cross-section capacity.
Key specifications
Conductor capacity: 16mm2
Mounting type: DIN rail
Connection method: Screw terminal
Color: Gray
Application: Industrial and commercial electrical panels
How to use
To install the terminal block, snap it securely onto a standard DIN rail until it clicks into place. Strip the insulation from your electrical wire to the appropriate length, insert the conductor into the terminal opening, and tighten the screw using a compatible screwdriver to ensure a firm connection. Ensure that the torque applied is sufficient to hold the wire securely without damaging the conductor strands. Multiple blocks can be placed side-by-side to create a terminal strip, and end clamps should be used to prevent lateral movement on the rail.
What to consider before purchase
Verify that your conductor size is compatible with the 16mm2 capacity
Ensure your mounting rail is a standard DIN rail type
Check if additional accessories like end plates or marking tags are required for your specific layout
Usage recommendations
Always ensure that the power supply is completely disconnected before performing any wiring or maintenance on the terminal blocks to prevent electrical hazards. Regularly inspect connections in high-vibration environments to ensure screws remain tightened to the manufacturer's recommended torque.
