What Are The Characteristics Of European Style Terminal Blocks?

As a key component in the field of electrical connections, European style terminal blocks have multiple significant characteristics. The following introduces them from four dimensions: structure, function, standards, and innovative applications:

1、 Structural and functional characteristics

Modular design

Adopting a modular structure, such as the world's first modular terminal block invented by Phoenix Contact, it can flexibly expand the cable connection angle, support 3.5mm, 3.81mm vertical and right angle plugs, adapt to 90 ° and 270 ° interfaces, and meet complex wiring requirements.

Efficient Connection Technology

Connect conductive parts through screws, springs, insertion and extraction, or push-pull methods. For example, screw terminals provide high clamping force, spring terminals simplify the installation process, plug-in terminals enhance flexibility, and push-pull terminals are suitable for high-frequency connection scenarios.

2、 Standardization and certification features

Following European standards

Strictly produced according to European specifications and certified by UL, ensuring that the products comply with safety regulations in the fields of industrial control, communication equipment, and HVAC (heating, ventilation, and air conditioning).

Compatibility Design

Supports both open and closed plugs, meeting the 5.0mm and 5.08mm centerline spacing standards. It can be stacked end-to-end without affecting the spacing, improving space utilization.

3、 Material and Performance Characteristics

Durable material

The shell is mostly made of flame-retardant grade UL94 V-0 PA66 insulation material, and the connector is made of highly conductive metal to ensure stable electrical performance.

Environmental adaptability

The working temperature range is wide from -40 ° C to+105 ° C, capable of withstanding 300 volts of voltage, 16 amperes of current, and a surge voltage of up to 2500V. It is suitable for harsh environments such as outdoors and ships.

4、 Innovative application features

New bipolar plug

After expanding the functionality, it supports additional cable connection angles and can be applied to scenarios such as control, input/output, and on-site wiring.

Intelligent integration

Some products reserve intelligent control interfaces for integration with automation systems, enabling remote monitoring and data analysis.

European style terminal blocks, with their standardized design, efficient connection technology, and environmental adaptability, have become the core components of electrical equipment, power systems, and automation control systems, promoting the development of electrical engineering towards safety and efficiency
