Universal terminal clamp OTH301-3 with one mounting hole 3xAl/Cu 70-300 mm², 1250A, 1000V MAC3301A14

Universal Connections for Demanding Installations

The OTH301-3 terminal block is a professional solution for directly connecting copper and aluminum conductors to switchgear equipment. Its design allows for the connection of three conductors with cross-sections ranging from 70 to 300 mm², ensuring a reliable electrical connection in applications with high current loads.

Versatility of Electrical Connections

The product supports various conductor types thanks to its flexible cross-section range:

• Stranded conductors with crimped ferrules from 70 to 240 mm²
• Multi-strand conductors in the range of 70 to 300 mm²
• Stranded conductors without cable lugs from 70 to 300 mm²

This versatility eliminates the need for additional adapters or transition pieces, simplifying the installation process and reducing material costs.

Compact Design with High Performance

Despite its compact dimensions (54 × 63 × 86 mm), the terminal block delivers impressive electrical parameters: The rated current reaches 1250A at a voltage of 1000V, making it suitable for high-power industrial applications. Its compact construction facilitates installation in confined switchboard spaces.

Two Connection Types in One Product

The terminal block is equipped with both a screw connection and a pin connection, providing installers with the flexibility to choose the optimal method for connecting conductors. This combination enables adaptation to various types of switchgear equipment and mounting preferences.

Simple Direct Mounting

The "direct" mounting method eliminates the need for additional fastening elements or adapters. A single mounting hole simplifies the installation process and ensures stable fixation within the switchboard enclosure.
