H & U  Type Screw Terminal Blocks

Secure Wire Connections. Brass Conductive Inserts. Multiple Insulation Materials.

H and U type terminal blocks are designed for connecting and extending electrical wires in lighting fixtures, appliances, electrical equipment and general wiring installations.

Featuring brass conductive inserts and screw-clamp connections, these terminal strips are available with PE, PP or PA insulating housings to meet different installation requirements.

Secure Screw-Clamp Connections

Each terminal position uses screw fastening to secure conductors inside a brass connection insert, providing a convenient connection that can be opened for maintenance or rewiring.

Key benefits include:

• Brass Conductive Inserts: Provide electrical conductivity and stable contact when properly installed.
• Screw-Clamp Fastening: Allows conductors to be secured and disconnected using a screwdriver.
• Multi-Pole Design: Organizes multiple independent wire connections in one strip.
• Multiple Sizes: Different wire capacities and current ratings for different applications.

H Type & U Type Options

H Type Terminal Blocks

Suitable for general electrical wiring and equipment connections, with H-series housing designs and multiple electrical ratings.

U Type Terminal Blocks

An alternative screw terminal strip design with different housing dimensions and connection sizes for electrical installation and maintenance.

Select the appropriate type according to the required dimensions, wire capacity, mounting arrangement and electrical rating.

PE, PP & PA Insulation Options

Different housing materials are available for different operating conditions.

• PE (Polyethylene): Flexible, economical insulation for general-purpose applications within its rated temperature range.
• PP (Polypropylene): A practical option offering a balance of rigidity, insulation properties and cost.
• PA (Polyamide): Suitable for applications requiring greater mechanical and temperature performance, depending on the specified material grade.

Typical Applications

• Lighting Fixtures: Internal wiring and lighting connections.
• Electrical Appliances: Wire connections inside compatible equipment.
• Control Equipment: Organized connections for suitable low-voltage circuits.
• Industrial Machinery: Internal equipment wiring and maintenance.
• Electrical Junction Boxes: Wire joining and extension within suitable enclosures.

Choose the Right Terminal Block

Select according to the wire cross-section, rated current, rated voltage, insulation material, operating temperature and installation dimensions.

Use an appropriate conductor preparation method and the specified screw tightening torque.

Frequently Asked Questions

1. What are H and U type terminal blocks used for?

They are screw-type terminal strips used to connect and extend electrical wires in lighting, appliances, electrical equipment and suitable low-voltage installations.

2. What is the advantage of brass conductive inserts?

Brass provides electrical conductivity and mechanical durability for screw-type connections when used within the specified ratings.

3. What is the difference between PE, PP and PA terminal blocks?

PE is generally selected for flexibility and economy, PP offers a balance of rigidity and cost, while PA grades can provide higher mechanical and temperature performance.

4. Can a 12-pole terminal strip be cut into shorter sections?

Some connector strips are designed to be cut into fewer positions. This must be confirmed for the selected housing design and installation requirements.

5. How do I choose the correct terminal block?

Check the wire cross-section, rated current and voltage, housing material, mounting dimensions and permitted operating temperature.
