Screw terminal connector 4 mm2 (grey) ESC-CBC.4 003903001

Universal rail connector for electrical connections

This threaded connector with a cross-section of 4 mm² is a reliable solution for connecting wires in electrical installations. Designed for mounting on a 35 mm DIN rail, it provides a solid and secure connection, finding application in both building and industrial installations. Its versatility will be appreciated by both electricians during project implementation and end-users who need a reliable and easy-to-use element for their installations.

Construction and parameters

The ESC-CBC.4 connector is made of high-quality thermoplastic material with flammability class V0, which guarantees safety even in difficult conditions. The two-level design with two terminals per level allows you to connect two wires simultaneously, increasing work efficiency. It provides a rated current of up to 45A with a cross-section of 4mm², and its impulse voltage withstand capacity is as high as 12kV. It accepts solid and stranded wires with a cross-section from 0.2 mm² to 6 mm². The possibility of using crimp ferrules (0.2…4 mm²) and the lack of necessity to use them (0.2…6 mm²) gives flexibility during installation. The gray housing makes it easy to identify and looks aesthetically pleasing in the switchgear cabinet.

Advantages and application

• Wide range of wire cross-sections: from 0.2 mm² to 6 mm², allowing adaptation to different types of installations.
• High resistance to external conditions: operating temperature range from -40°C to +100°C ensures reliable operation in various environments.
• Safety: insulating material with flammability class V0 minimizes the risk of fire.
• Easy installation: possibility of mounting on a standard 35 mm DIN rail facilitates and speeds up installation.
• Versatility: ideal for connections in building, industrial and automation installations.
• Compatibility with other elements: compatible with other elements of the ETI systems, allowing for the creation of comprehensive solutions.
• Impulse strength: high impulse voltage withstand (12kV) protects against damage caused by overvoltage.

The ESC-CBC.4 connector finds application wherever a solid and safe connection of electrical wires is required – from switchboards in homes and commercial buildings, to control cabinets in industry. Thanks to its versatility and ease of installation, it is an ideal choice for both professionals and people performing electrical work independently.
