Why Choose the VEM4 [1SBN030111R1000]
The VEM4 is a combined mechanical and electrical interlock kit designed for side-by-side interlocking of two AF09 to AF38 or AFC09 to AFC38 contactors without increasing their overall width. The set comprises a VM4 mechanical interlock unit with two BB4 fixing clips and a VE4 electrical interlock block featuring an A2-A2 coil connection. Attaching the VE4 block to the front of the contactors utilises their built-in normally closed interlocking contacts, significantly reducing wiring requirements by up to 50% compared to traditional electrical interlocking methods. It is essential to connect the VE4 block via the A2-A2 terminals to comply with the specified electrical connection diagram.
