Terminal branch block Irna 4x10mm for electrical connections, model 4X10MM2

Irna 4x10mm terminal branch block is a compact four-way connector designed to join and distribute electrical conductors with a cross-section of 10 mm². The component enables secure branching in installations, control panels and junction boxes, allowing tidy wiring, simplified load splitting and straightforward maintenance access without altering circuit continuity.

Advantages

The branch block offers reliable mechanical and electrical contact for four conductors of the specified size, built to maintain stable connection under normal operating conditions. Its compact form factor reduces space requirements inside enclosures and panels, while a clear layout facilitates fast identification and routing of conductors during installation or servicing. Materials and construction provide consistent performance for standard low-voltage distribution tasks.

Suitable for

• Power distribution and branching in control panels
• Junction boxes and electrical cabinets
• Tidy wiring and cable organization in industrial or residential installations
• Splitting loads among multiple circuits with 10 mm² conductors

Key specifications

• Number of ways: 4 connection points
• Conductor cross-section: up to 10 mm² per connection
• Connection type: fixed terminal block for secure conductor clamping
• Typical application voltage: suitable for standard low-voltage electrical installations (check project requirements)
• Construction: compact footprint for mounting inside panels and junction boxes

How to use

Strip insulation from each conductor to the length recommended by installation standards, insert the stripped end into the terminal opening and secure it according to the terminal’s clamping method (screw or spring clamp). Ensure each 10 mm² conductor is fully seated and that clamps are tightened to the torque specified for the terminal type. Verify continuity and correct polarity where required, and arrange connected conductors neatly to avoid strain or contact with sharp edges.

Usage recommendations

Follow applicable national and local electrical codes during selection and installation. Confirm that conductor size, current rating and environmental conditions match the connector’s intended use. Use appropriate tools for stripping and tightening, and perform insulation and continuity checks after installation to ensure safe operation.
