MOREK OTH301-3 Universal Terminal Clamp, 3xAl/Cu 70-300 mm², 1250A, 1000V, Single Mounting Hole

The MOREK OTH301-3 is a high-performance universal terminal clamp engineered for secure and efficient electrical connections in demanding industrial environments. This robust component is designed to accommodate three aluminum or copper conductors, providing versatility for various power distribution setups. With a capacity to handle conductors ranging from 70 to 300 mm², it ensures reliable conductivity and mechanical stability for heavy-duty electrical systems.

Advantages

The primary advantage of this terminal clamp lies in its exceptional current-carrying capacity of 1250A and a voltage rating of 1000V, making it suitable for high-power applications. Its universal design allows for the flexible use of both aluminum and copper conductors, simplifying inventory requirements. The single mounting hole configuration facilitates quick and straightforward installation within electrical panels, saving time during assembly and maintenance processes.

Suitable for

• Industrial power distribution systems
• Electrical switchgear and control panels
• Large-scale electrical infrastructure projects
• Connecting heavy-duty aluminum or copper cables

When it may not be suitable

This terminal clamp is not intended for use with conductors smaller than 70 mm² or larger than 300 mm², as this may compromise the integrity of the connection. It is also not suitable for applications requiring specialized environmental protection beyond standard industrial panel enclosures.

Key specifications

• Conductor capacity: 3 ports for 70–300 mm² conductors
• Material compatibility: Aluminum and copper
• Maximum current: 1250A
• Maximum voltage: 1000V
• Mounting: Single hole design

How to use

To install the MOREK OTH301-3, ensure the power supply is disconnected. Prepare the conductors by stripping the insulation to the required length. Insert the conductors into the designated ports and tighten the screws to the manufacturer's specified torque to ensure a secure mechanical and electrical connection. Mount the clamp onto the designated surface using the single mounting hole provided, ensuring it is firmly fixed before restoring power.

What to consider before purchase

• Verify that your conductor cross-section falls within the 70–300 mm² range.
• Ensure the mounting surface is compatible with the single-hole installation method.
• Confirm that the electrical system requirements do not exceed the 1250A and 1000V ratings.

Usage recommendations: Always use a calibrated torque wrench during installation to ensure optimal contact pressure and prevent damage to the conductors or the terminal clamp. Regularly inspect connections in high-vibration environments to maintain long-term reliability.
