The VEM4 is a mechanical and electrical interlock set designed for interlocking two AF09…AF38 or AFC09…AFC38 contactors side-by-side without increasing the overall width. The set includes a VM4 mechanical interlock unit with two BB4 fixing clips, along with a VE4 electrical interlock block featuring an A2–A2 connection. When mounted on the front of the contactors, the VE4 block utilizes the two built-in N.C. interlocking contacts to connect the coils, reducing wiring requirements by up to 50% compared to conventional electrical interlocking methods. To ensure proper operation, the VE4 block must be used with the A2–A2 connection, in accordance with the recommended wiring diagram.
