£64.72
The ABB 1SBN030210R1000 VE5-2 is a compact mechanical and electrical interlock unit designed for ABB A-series contactors, providing reliable interlocking of two contactors in reversing, changeover and star-delta starter applications. It combines mechanical interlocking with integrated electrical interlocking contacts to improve the safety and reliability of industrial motor control systems.
This interlock unit is installed between two compatible ABB contactors to prevent simultaneous operation. The VE5-2 includes built-in normally closed interlocking contacts, allowing electrical interlocking of contactor coils while the mechanical mechanism provides physical protection against incorrect switching sequences.
With compatibility across ABB A contactor ranges including A45 to A110 models, the VE5-2 provides a dependable solution for industrial control panels, motor starters and automation systems requiring coordinated contactor operation.
Mechanical and electrical interlock units such as the ABB VE5-2 provide dependable switching coordination in contactor-based motor control systems. The mechanical mechanism prevents both contactors from closing simultaneously, while the integrated auxiliary contacts enable electrical interlocking of the contactor coils.
The VE5-2 is designed for machine builders, panel builders and automation engineers requiring robust contactor control solutions for reversing motors, changeover systems and industrial starter applications.
