£27.97
The ABB 1SBN030113R1000 VEM4K is a compact mechanical and electrical interlock set designed for ABB AF and AFC contactors, providing reliable interlocking of two contactors in reversing, changeover and motor starter applications. As part of the ABB contactor accessory range, it combines mechanical interlocking with integrated electrical interlocking functionality to improve the safety and reliability of industrial control systems.
The VEM4K set includes a mechanical interlock unit with fixing clips and an electrical interlock block with A2-A2 connection, allowing two contactors to be interlocked without increasing the overall contactor assembly width. This design helps reduce wiring requirements while maintaining dependable contactor coordination.
Designed for ABB AF09 to AF38 and AFC09 to AFC38 contactors with Push-In Spring terminals, the VEM4K provides a space-saving solution for industrial motor control panels, reversing starters and automation assemblies.
Mechanical and electrical interlock sets such as the ABB VEM4K provide coordinated switching control in contactor-based motor starter systems. The mechanical interlock prevents both contactors from closing simultaneously, while the electrical interlock block provides integrated coil circuit interlocking.
The VEM4K is designed for machine builders, panel builders and automation engineers requiring compact, reliable solutions for reversing and changeover contactor assemblies.
