Crimp ring terminal Ergom KM 25/12 copper – model E11KM-01010103700

Ergom KM 25/12 copper crimp ring terminal is designed to provide a reliable mechanical and electrical connection for copper conductors with a cross-section of 25 mm² and a 12 mm internal ring diameter. The terminal is suited for power distribution, grounding and panel wiring where a solid ring-type termination is required. Constructed from copper, the terminal offers low electrical resistance and good conductivity for permanent or maintenance connections in low- and medium-voltage installations.

Advantages

The copper construction ensures low contact resistance and stable conductivity over time. The ring contact design allows secure bolted connections that resist vibration and loosening. The crimp barrel is sized for a 25 mm² conductor to provide a compact, mechanically robust termination when properly crimped. The terminal's standardized ring inner diameter fits common mounting studs and bolts used in electrical panels and grounding systems.

Suitable for

• Power distribution busbars and terminal blocks
• Grounding and earthing connections
• Control panels and switchgear wiring
• Industrial machinery and electrical cabinets

Key specifications

• Material: copper
• Conductor capacity: 25 mm²
• Ring inner diameter: 12 mm
• Contact type: ring (oczkowa)
• Connection method: crimping

How to use

Prepare the copper conductor by stripping insulation to the appropriate length so it fully enters the crimp barrel. Insert the conductor into the barrel and position the ring so the conductor is fully seated. Use a suitable crimping tool sized for 25 mm² terminals and apply a proper crimping force to form a gas-tight mechanical connection. After crimping, place the ring over the mounting stud or bolt and secure with the appropriate nut and washer to ensure a firm, low-resistance contact.

Usage recommendations

Use correct crimping dies and tools rated for 25 mm² copper terminals, inspect crimps visually and mechanically, and where required apply anti-oxidation compound on exposed copper connections in corrosive environments. Ensure torque values on the mounting hardware match installation standards for the stud or bolt size.
