BER38-4 - Reversing starter connection element 1SBN082311R1000

Connection elements for reversing starters – reliability and easy installation

This connection element, designated BER38-4, is a key component in the construction of reversing starters and star-delta systems. Designed for efficient and safe motor control, it is an integral part of overload and short-circuit protection systems. Its use translates to increased reliability of the entire starting system.

This element enables quick and easy installation of contactors, eliminating the need to disconnect the wiring of motor circuit breakers during installation or disassembly. This significantly reduces downtime and facilitates installation servicing. A complete set of connection elements allows for the construction of advanced motor control systems, providing flexibility in configuration selection.

Construction and application

This product is a connecting bridge, dedicated to working with motor circuit breakers and contactors. Its design allows for easy creation of complete control circuits, including reversing and star-delta systems. The possibility of use with motor circuit breakers up to 100A makes it a universal solution for various industrial applications. Additionally, compatibility with 35 mm rails eliminates the need for additional mounting plates, simplifying the installation process.

It is worth noting the possibility of mechanical locking of contactors using the VM4 unit or the VEM4 kit (containing mechanical and electrical locking), which increases work safety and minimizes the risk of accidental starting or stopping of the motor. The use of this connection element translates to optimization of the configuration of auxiliary contact blocks and increased device reliability thanks to the use of AF contactors with a wide range of operating voltages and built-in overvoltage protection.
