• Maximum current capacity: 80 A at 400 V for 16 mm² input
• Connection capacity: 1 x 6 to 25 mm² and 8 x 1.5 to 16 mm²
• Length: 73 mm
• Mounting: Compatible with M4 screws
• Standards: Compliant with IEC 60998-2-1

How to use

The terminal block is supplied ready for use with screws in an untightened position. To install, mount the block securely within the distribution board using the appropriate M4 screws. Strip the insulation from your conductors according to the required length, insert the wires into the designated terminals, and tighten the screws firmly to ensure a solid electrical contact. Ensure that the total current load does not exceed the specified limits for the respective conductor sizes to prevent overheating.

What to consider before purchase

• Verify that the conductor sizes in your installation match the 1.5 mm² to 25 mm² range.
• Ensure the distribution board has sufficient space to accommodate the 73 mm length of the block.
• Confirm that the maximum current requirements of your circuit do not exceed the rated 80 A or 100 A limits.

Usage recommendations

Always ensure that the power supply is completely disconnected before performing any installation or maintenance work on the terminal block to prevent electrical shock.
