Busbar fork-type 3P 80A 12 mm² 18 modules ETI-Polam IZ12/3F/18

Fork-type busbar Eti-Polam IZ12/3F/18 is a three-pole conductive link designed for distribution boards and modular switchgear. It supports a rated current of 80 A and is compatible with conductors up to 12 mm². The busbar is arranged to occupy 18 DIN-modules, providing a compact and stable connection point for circuit breakers and other modular protective devices in residential and light-commercial installations.

Advantages

The fork configuration ensures fast and reliable connection to device terminals while reducing installation time. Constructed to fit standard DIN-module spacing, the busbar keeps wiring neat and aligned across three poles. Its rated current of 80 A and compatibility with 12 mm² conductors allow use with commonly installed cables without the need for adapters. The rigid form factor minimizes movement and ensures consistent electrical contact under typical panel conditions.

Suitable for

• Three-pole circuit breaker assemblies in residential distribution boards
• Compact commercial switchgear with 18-module layouts
• Replacing or extending existing fork-type busbar connections
• Installations using conductors up to 12 mm² requiring up to 80 A per pole

When it may not be suitable

This busbar is not suitable for applications requiring higher current ratings than 80 A or for conductors larger than 12 mm². It is designed for standard 18-module layouts; panels with different module spacing or non-modular equipment may require custom busbars or alternative connection methods. For environments with specific corrosion, vibration, or temperature requirements, consult applicable standards to confirm suitability.

Key specifications

• Number of poles: 3 (three-pole)
• Rated current per pole: 80 A
• Maximum conductor cross-section: 12 mm²
• Module width: occupies 18 DIN-modules
• Connection type: fork (spade) terminals

How to use

Mount the busbar in the distribution board so that it aligns with the terminal screws of the corresponding three-pole devices. Ensure power is disconnected before installation. Insert the conductor into the fork terminal or secure the busbar fork onto the device terminal according to the device manufacturer's torque recommendations, then tighten terminal screws evenly to establish reliable contact. Verify mechanical stability and electrical continuity after installation and restore power only after confirming correct connections.

What to consider before purchase

• Confirm your panel layout uses an 18-module spacing that matches the busbar length
• Verify required current rating does not exceed 80 A per pole
• Ensure conductor size does not exceed 12 mm² for direct connection
• Check compatibility of terminal screw sizes and device terminal geometry

Usage recommendations

Use the busbar in dry, indoor switchgear environments and follow local electrical installation standards. Tighten terminals to the torque specified by the device manufacturer, route conductors to avoid mechanical strain on the fork connections, and perform continuity and insulation checks after installation.
