## Long description

The Ergom KOI 50/12 insulated ring terminal is a high-quality electrical component designed to provide secure and reliable connections for heavy-duty wiring. Engineered specifically for conductors with a cross-section of 50 mm², this terminal features a 12 mm stud hole, making it compatible with a wide range of industrial bolts and connection points. The integrated insulation provides essential protection against short circuits and accidental contact, ensuring safety in demanding electrical environments.
Advantages
This ring terminal offers exceptional mechanical strength and electrical conductivity, which are critical for maintaining stable performance in power distribution systems. The robust design minimizes resistance at the connection point, reducing heat generation during operation. Its insulation is crafted from durable materials that resist environmental stress, providing long-term reliability for professional electrical installations and control panel wiring.
Suitable for
Industrial electrical installations
Power distribution control panels
Heavy-duty machinery wiring
Low-voltage electrical systems
When it may not be suitable
This terminal is not intended for use with conductors that do not match the specified 50 mm² cross-section, as improper sizing can lead to loose connections and overheating. It is also unsuitable for high-voltage applications exceeding the rated insulation limits or for environments involving extreme chemical exposure that could degrade the insulation material.
Key specifications
Conductor cross-section: 50 mm²
Stud hole diameter: 12 mm
Insulation type: Integrated sleeve
Material: High-conductivity copper with protective coating
How to use
To install the Ergom KOI 50/12 terminal, first strip the insulation from the end of the 50 mm² conductor to the appropriate length. Insert the conductor fully into the barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for this terminal size to ensure a gas-tight mechanical bond. Once crimped, place the ring over the corresponding 12 mm stud and secure it firmly with a nut or bolt to ensure optimal electrical contact.
What to consider before purchase
Verify the conductor gauge matches the 50 mm² requirement
Ensure the stud size is exactly 12 mm for a proper fit
Confirm the availability of a compatible heavy-duty crimping tool
Usage recommendations
Always ensure that the crimping tool is properly calibrated for the specific terminal type to prevent connection failure. Regularly inspect connections in high-vibration environments to ensure that fasteners remain tight and secure.
