How does an electrical terminal block work?
An electrical terminal block, or distribution terminal block, combines several connections in a single modular device. It can be easily mounted on a DIN rail in your electrical panel. This solution optimises space while ensuring reliable and secure connections.
The distribution terminal block functions as a conductor bar with several connection points.
Each connection accommodates a cable with a cross-section compatible with the terminal block. The current is distributed evenly to all connected outlets.
Modern terminal blocks incorporate IP2X protection against direct contact. This protection prevents objects from being inserted into live parts. Your safety is thus guaranteed during maintenance work.
The connection is made by screw clamping or by an automatic system, depending on the model. Screw systems provide a robust connection for large cross-sections. Automatic connections speed up installation for small cross-sections.
What is the difference between a terminal and a terminal block?
An electrical terminal is a single connection point for connecting a single cable. It only serves to clamp and hold the conductor in place. Its capacity is limited to a single connection.
A distribution terminal block combines several terminals in a single device. It allows multiple cables to be connected to the same phase, neutral or earth. This design greatly simplifies the organisation of the electrical panel.
Choosing your electrical terminal block
The cable cross-section determines the choice of the appropriate distribution terminal block. Check that the terminal block's cross-section range corresponds to your cables. Models generally cover 1.5mm² to 35mm² depending on the reference.
The number of connections required directly influences your selection. Calculate your current needs precisely and allow for a margin for future developments. This foresight avoids costly modifications later on.
IP2X protection is an essential safety standard for modern terminal blocks. This protection prevents accidental contact with live parts. Your installation will therefore comply with current safety standards.
Compatibility with your electrical panel ensures quick and easy installation. Terminal blocks are mounted on standard 35 mm DIN rails. This universal compatibility greatly facilitates installation.
