EN63 terminal blocks are electrical connectors which allow two or more wires to be connected with each other. They are typically used in power distribution applications, such as distribution and routing of electricity between switchboards, motors, turbines, and other process equipment. They are also used in residential or commercial installations, where the primary function is to ensure the safe protection of personnel, stock and other valuable resources.

These terminal blocks have been designed in accordance with IEC60850-1 International Standard for Low Voltage Electrical Devices, complying with the safety requirements of the European Community. This ensures that the terminal blocks are suitable for use in safety-related circuits. They are manufactured in accordance with EN63 standard, which is the standard for insulating material (IM) used for electrical insulation and mechanical protection of electrical terminals of this type.

　EN63 terminal blocks are available in various sizes and shapes to accommodate different wiring requirements. They can be found in a variety of colours and with or without indicators or markers. The most common type is the standard terminal block, which allows the connection of two wires with different current ratings. Special versions are also available which can handle three or four-wire connections, as well as switching or safety functions.

The working principle of EN63 terminal blocks is based on the insertion of the wire into the contact terminal, which is fastened to the insulated housing with screws or rivets. The connected contacts are then secured with a clamping device to ensure a good electrical contact. The electrical connection between the contacts is then kept secure with special locking devices, such as latches, nuts, screws or rivets. The clamping device can be adjustable to provide the necessary tension and ensure perfect connectivity.

The terminal blocks are highly reliable and durable and can be used in a variety of hazardous environments, including wet and dusty places. They are resistant to mechanical damage, corrosion, and extreme temperatures, making them suitable for a wide range of power distribution applications. The most common power distribution applications involve AC and DC power, which include lighting, heating and air conditioning, and in some cases, process automation.

EN63 terminal blocks are also available with multiple pole arrangements. This allows for the connection of multiple wires or cables at the same time. For example, if an electrical device requires several wires to be connected, the multiple poles can be used to ensure the optimal level of power distribution and safety of the circuit, as well as eliminating the need for extra wiring or cabling.

In conclusion, EN63 terminal blocks are reliable and convenient electrical connectors which are suitable for a wide range of power distribution applications. They are designed in accordance with IEC60850-1 and EN63 standards, ensuring proper insulation and mechanical protection for the user. They are also available in a variety of sizes and shapes, making them suitable for use in hazardous environments and for a variety of power distribution applications.
