Intercable ICALCU12CS arandela plana de cobre M12, 30 mm de diámetro exterior, para terminales de hasta 400 mm², desnuda

Flat copper washers for M12 bolts, engineered for high-current electrical connections up to 400 mm² cable cross-section. The 30 mm outer diameter provides a large contact surface, ensuring low resistance and excellent conductivity in professional installations.

Advantages

Made from plain copper, these washers offer superior electrical conductivity and are ideal for cable lug terminations. The precise M12 inner diameter ensures a secure fit on standard bolts, while the 30 mm OD distributes clamping force evenly, preventing damage to cable lugs and ensuring a reliable, long-lasting connection.

Suitable for

• Electrical panel installations
• Cable lug terminations up to 400 mm²
• High-current power distribution
• Professional electrical installations requiring RoHS compliance

Key specifications

• Material: Copper
• Nominal bolt size: M12
• Outer diameter: 30 mm
• Inner diameter: approx. 13 mm
• Surface finish: Plain (uncoated)
• Compatible cable cross-section: up to 400 mm²

Recommendations

For optimal performance, pair with copper cable lugs and ensure proper torque on M12 bolts. These washers are essential for maintaining low-resistance connections in demanding electrical environments.
