Product list Feed-through terminal blocks
Compact feed-through terminal blocks with screw connection in various sizes are ideal for both solid and stranded conductors.
Whatever you want: the large cross-section range, flexible bridging options, and optimum marking options make feed-through terminal blocks the universal connection technology solution.
Your advantages
- Easy to operate and use, thanks to proven screw connection
- Universal use – Connection of small to very large conductor cross sections
- Space saving, thanks to the compact design
Two terminal points – Compact design
Feed-through terminal blocks are characterized by two terminal points and a compact design. Ground terminals of the same shape are available to match the feed-through terminal blocks.
All bridgeable terminal blocks can be bridged together easily with multi-conductor and function terminals.
UBAL universal terminal blocks for aluminum conductors
The new UBAL series of universal terminal blocks has been tested in accordance with the latest standards and is particularly suited to applications such as photovoltaics.
These universal terminal blocks make it possible to wire aluminum conductors and copper wires together in the same terminal block.
UBAL terminal blocks are available in four cross-section sizes, enabling aluminum conductors from 6 mm² to 240 mm² to be connected, along with copper wires from 2.5 mm² to 240 mm².
High-quality aluminum alloy
The metal parts of the universal terminal blocks are produced from high-quality aluminum alloys. A lead-free tin coating on the clamping parts and screws enable aluminum conductors and copper wires to be connected. The terminal points are able to accommodate both rigid and multi-stranded conductors.
Pre-lubricated contact chambers
The terminal points are already coated with an antioxidant, simplifying the aluminum conductor mounting process. Another advantage of the pre-lubricated contact chambers is the maintenance-free contact point, since it does not need to be retightened.
Top quality
The universal terminal blocks are certified for the connection of aluminum conductors in accordance with EN 61238-1 (Class A). Furthermore, they are approved in accordance with IEC 60947-7-1 and are suited in particular to applications such as photovoltaics. Therefore, these terminal blocks are tested for an operating temperature of 90°C.
High level of safety
The touch-protection caps cover the clamping space and the screw opening of the universal terminal blocks. The inadvertent touching of metal parts or opening of the terminal points is thus prevented.
Large-surface marking option
A large area of the universal terminal blocks can be marked, thus enabling clear wiring.
Convenient mounting
The universal terminal blocks can be mounted on the 35 mm DIN rail or directly on the mounting plate. Only the UBAL 240 is suitable for direct mounting alone, thanks to its high tightening torque.
Simple fixing of conductors
Allen screws reliably transfer the various torques for aluminum conductors and copper wires.
